QUANTITATIVE APTITUDE

Question 1 of 50

1. Question
1 points
The respective ratio between the present ages of Ram,Rohan and Raj is 3 : 4 : 5. if the average of their presentages is 28 yr then what would be the sum of the ages of
Ram and Rohan together after 5 yr?
- 45 yr
- 55 yr
- 52 yr
- 59 yr
- None of these
Correct

Let the ages of Ram, Rohan and Raj be 3 x,4 x and 5 x
respectively,
Then,

$\frac{3 x+4 x+5 x}{3}$ =28

$\Rightarrow$ 4 x=28

$\Rightarrow x=\frac{28}{4}$ =7 yr

So, the present ages of Ram and Rohan together

=3 x+4 x

=7 x= $7\times 7$

= 49 yr

Hence, the sum of ages of Ram and Rohan together
after 5 yr

=49+ $5\times 7$

=49+10

=59 yr

Incorrect

Let the ages of Ram, Rohan and Raj be 3 x,4 x and 5 x
respectively,
Then,

$\frac{3 x+4 x+5 x}{3}$ =28

$\Rightarrow$ 4 x=28

$\Rightarrow x=\frac{28}{4}$ =7 yr

So, the present ages of Ram and Rohan together

=3 x+4 x

=7 x= $7\times 7$

= 49 yr

Hence, the sum of ages of Ram and Rohan together
after 5 yr

=49+ $5\times 7$

=49+10

=59 yr
Question 2 of 50

2. Question

Raman scored 456 marks in an exam and Seeta got54 per cent marks in the same exam which is 24 marks lessthan Raman. If the minimum passing marks in the exam is34 percent,then how much more marks did Raman score than the minimum passing marks?
- 184
- 196
- 190
- 180
- None of these
Correct

Let the total marks of the exam be x.
Then,

$x\times \frac{54}{100}$ =456-24

$\Rightarrow �x\times \frac{54}{100}$ =432

$\Rightarrow �x\times \frac{432\times 100}{54}$ =800

$\therefore$ Minimum passing marks

= $�800\times \frac{34}{100}$

=272

Hence, required more marks get by Raman
= 456 -272
= 184

In the following questions: two equations numbered I ond II are given. You have to :. solve both the equations and-

I. $(x^{\frac{7}{5}}\div 9)=169\div x^{\frac{3}{5}}$

II. $y^{\frac{1}{4}}\times y^{\frac{1}{4}}\times 7=273\div y^{\frac{1}{2}}$
- if x > y
- if x ≥ y
- if x < y
- if x ≤ y
- if x=y or the relationship cannot be established
Correct

From Eq .(i),

$\left ( x^{\frac{7}{5}}\div 9 \right )=169\div x^{\frac{3}{5}}$

$\Rightarrow x^{\frac{7}{5}+^{\frac{3}{5}}}=9\times 169$

$\Rightarrow x^{2}=1521$

$\Rightarrow x=\sqrt{1521}=\pm 39$

From Eq. (ii),

$y^{\frac{1}{4}}\times y^{\frac{1}{4}}\times 7=273\div y^{\frac{1}{2}}$

$\Rightarrow y(^{\frac{1}{4}}+^{\frac{1}{4}})-\frac{1}{2}=\frac{273}{7}$

$\Rightarrow y^{0}=39$

$\Rightarrow$ y=39

Hence, x

≤ y

Incorrect

From Eq .(i),

$\left ( x^{\frac{7}{5}}\div 9 \right )=169\div x^{\frac{3}{5}}$

$\Rightarrow x^{\frac{7}{5}+^{\frac{3}{5}}}=9\times 169$

$\Rightarrow x^{2}=1521$

$\Rightarrow x=\sqrt{1521}=\pm 39$

From Eq. (ii),

$y^{\frac{1}{4}}\times y^{\frac{1}{4}}\times 7=273\div y^{\frac{1}{2}}$

$\Rightarrow y(^{\frac{1}{4}}+^{\frac{1}{4}})-\frac{1}{2}=\frac{273}{7}$

$\Rightarrow y^{0}=39$

$\Rightarrow$ y=39

Hence, x

≤ y
Question 4 of 50

4. Question
1 points
In the following questions: two equations numbered I and II are given. You have to :. solve both the equations and-

II. $4y^{3}=(589\div 4)+5y^{3}$
- if x >y
- if x ≥ y
- if x < y
- if x ≤ y
- if x = y or the relationship cannot be established
Correct

From Eq. (i),

$x^{3}=\frac{(2)^{5}+(11)^{3}}{6}$

$\Rightarrow x^{3}=\frac{32+1331}{6}$

$\Rightarrow x^{3}=\frac{1363}{6}$ = 227.17

$\Rightarrow x=3\sqrt{227.17}$

From Eq. (ii),

$4y^{3}=(-589\div 4)+54^{3}$

$\Rightarrow y^{3}=\frac{589}{4}$ =147.25

$\Rightarrow y=3\sqrt{147.25}$

Hence, x > y

Incorrect

From Eq. (i),

$x^{3}=\frac{(2)^{5}+(11)^{3}}{6}$

$\Rightarrow x^{3}=\frac{32+1331}{6}$

$\Rightarrow x^{3}=\frac{1363}{6}$ = 227.17

$\Rightarrow x=3\sqrt{227.17}$

From Eq. (ii),

$4y^{3}=(-589\div 4)+54^{3}$

$\Rightarrow y^{3}=\frac{589}{4}$ =147.25

$\Rightarrow y=3\sqrt{147.25}$

Hence, x > y

- Rs.1660
- Rs.1860
- Rs.2600
- Cannot be determined
- None of these
Correct

Suppose the cost of one Chair = C
and the cost of one Table = ?
Then,
5 C+3'T=3110 ....(i)
and
T -C = 210 or T =210 + c ...(ii)
On putting value of T in Eq. (i),
5 c+3(210+c)=3110

$\Rightarrow$ 5 C+630+3 C=3110

$\Rightarrow$ 8 C =3110-630

$\Rightarrow C= \frac{2480}{8}$ =Rs.310

$\therefore$ Cost of one Table (T) = 210 + 310
= Rs. 520

Hence, the cost of two Tables and two Chairs.
=2 T +2 C
= $2\times 520+2\times 310$

= 1040 + 620
=Rs.1660

Incorrect

On putting value of T in Eq. (i),
5 c+3(210+c)=3110

$\Rightarrow$ 5 C+630+3 C=3110

$\Rightarrow$ 8 C =3110-630

$\Rightarrow C= \frac{2480}{8}$ =Rs.310

$\therefore$ Cost of one Table (T) = 210 + 310
= Rs. 520

Hence, the cost of two Tables and two Chairs.
=2 T +2 C
= $2\times 520+2\times 310$

= 1040 + 620
=Rs.1660

- if x > y
- if x ≥ y
- if x < y
- if x ≤ y
- if x = y or the relationship cannot be established
Correct

From Eq. (i), $\sqrt{1225}x+\sqrt{4900}$ =0
$\Rightarrow$ 35 x+70=0
$\Rightarrow$ x=-2
From Eq. (ii),
$81\tfrac{1}{4}y+343\tfrac{1}{3}$ =0
$\Rightarrow$ 3y+7=0
$y=\frac{-7}{3}=-2\frac{1}{3}$
Hence,X=Y

Incorrect

From Eq. (i), $\sqrt{1225}x+\sqrt{4900}$ =0
$\Rightarrow$ 35 x+70=0
$\Rightarrow$ x=-2
From Eq. (ii),

II. $^{y3}$ +9.68+5.64=16.95
- if x > y
- if x ≥ y
- if x < y
- if x ≤ y
- if x=y or the relationship cannot be established
Correct

From Eq. (i),
$\frac{18}{^{x2}}+\frac{6}{^{x2}}-\frac{12}{^{x2}}=\frac{8}{^{x2}}$
$\Rightarrow \frac{6}{^{x2}}+\frac{6}{x}-\frac{8}{^{x2}}$ =0
$\Rightarrow -\frac{2}{^{x2}}+\frac{6}{x}$ =0
$\Rightarrow \frac{2}{^{x2}}=\frac{6}{x}$
$\Rightarrow x=\frac{2}{6}=\frac{1}{3}$ =0.33
From Eq. (ii),
$^{y3}$ +9.68+5.64=16.95
$\Rightarrow ^{y3}$ =16.95-(9.68+5.64)
$\Rightarrow ^{y3}$ =16.95-15.32
$\Rightarrow ^{y3}$ =1.63
$\Rightarrow y= 3\sqrt{1.63}$ = 1.176
Hence,y > x

Incorrect

From Eq. (i),
$\frac{18}{^{x2}}+\frac{6}{^{x2}}-\frac{12}{^{x2}}=\frac{8}{^{x2}}$
$\Rightarrow \frac{6}{^{x2}}+\frac{6}{x}-\frac{8}{^{x2}}$ =0
$\Rightarrow -\frac{2}{^{x2}}+\frac{6}{x}$ =0
$\Rightarrow \frac{2}{^{x2}}=\frac{6}{x}$
$\Rightarrow x=\frac{2}{6}=\frac{1}{3}$ =0.33
From Eq. (ii),
$^{y3}$ +9.68+5.64=16.95
$\Rightarrow ^{y3}$ =16.95-(9.68+5.64)
$\Rightarrow ^{y3}$ =16.95-15.32
$\Rightarrow ^{y3}$ =1.63
$\Rightarrow y= 3\sqrt{1.63}$ = 1.176
Hence,y > x

I. $12^{x2}+11x+12=10x^{2}+22x$
II. $13y^{3}-18y+3=9y^{2}-10y$
- if x > y
- if x ≥ y
- if x < y
- if x ≤ y
- if x =y or the relationship cannot be established
Correct

From Eq. (i),
$12^{x2}+11x+12=10^{x2}+22x$
$\Rightarrow 2x^{2} -11x+12=0$
$\Rightarrow 2x^{2} -8x-3x +12=0$
$\Rightarrow 2x(x-4)-3(x-4)=0$
$\Rightarrow (2x-3)(x-4)=0$
Then,
(2x-3)=0 $\Rightarrow x=\frac{3}{2}$
and
(x-4)=0 \Rightarrow x = 4
From Eq. (ii),
$13y^{2}-18y+3=9y^{_{3}}-10y$
$\Rightarrow 4y-8y+3=0$
$\Rightarrow 4y-6y-2y+3=0$
$\Rightarrow 2y(2y-3)-1(2y-3)= 0$
$\Rightarrow (2y-1)(2y-3)= 0$
Then,
(2y-1)=0 $\Rightarrow y=\frac{1}{2}$
and
(2y-3)=0 $\Rightarrow y=\frac{3}{2}$
Hence, x ≥ y

Incorrect

From Eq. (i),
$12^{x2}+11x+12=10^{x2}+22x$
$\Rightarrow 2x^{2} -11x+12=0$
$\Rightarrow 2x^{2} -8x-3x +12=0$
$\Rightarrow 2x(x-4)-3(x-4)=0$
$\Rightarrow (2x-3)(x-4)=0$
Then,
(2x-3)=0 $\Rightarrow x=\frac{3}{2}$
and
(x-4)=0 \Rightarrow x = 4
From Eq. (ii),
$13y^{2}-18y+3=9y^{_{3}}-10y$
$\Rightarrow 4y-8y+3=0$
$\Rightarrow 4y-6y-2y+3=0$
$\Rightarrow 2y(2y-3)-1(2y-3)= 0$
$\Rightarrow (2y-1)(2y-3)= 0$
Then,
(2y-1)=0 $\Rightarrow y=\frac{1}{2}$
and
(2y-3)=0 $\Rightarrow y=\frac{3}{2}$
Hence, x ≥ y

The total area of a circle and a rectangle is equal to 1166 sq cm. The diameter of the circle is 28 cm. What is the sum of the circumference of the circle and the perimeter of the
rectangle if the length of the rectangle is 25 cm?
- 186 cm
- 182 cm
- 184 cm
- Cannot be determined
- None of these
Correct

The area of the circle= $\pi r^{2}$

= $\frac{22}{7}\times 14\times 14$

=616 sq cm

Let the length and breadth of the rectangle be x cm
and y cm respectively.
Then,

$x\times y$ =1166-616

$\Rightarrow 25\times y$ =550

$\Rightarrow y=\frac{550}{25}$ =22 cm

$\therefore$ Perimeter of the rectangle

=2(x+y)

=2(25+22)

=94 cm

and circumference of the circle

= $2\pi r$

= $2\times \frac{22}{7}\times 14$

= 88 cm

Hence, required sum

=94+88=182 cm

Smallest angle of a triangle.is equal to two-third the smallest angle of a quadrilateral. The ratio between the, angles of the quadrilateral is 3 : 4 : 5 : 6. Largest angle of the
triangle is twice its smallest angle. What is the sum of second largest angle of the triangle and largest angle of the quadrilateral ?
- $160^{\circ}$
- $180^{\circ}$
- $190^{\circ}$
- $170^{\circ}$
- None of these
Correct

Let the angles of the quadrilateral be 3 x,4 x,5 x and 6 x respectively.
Then,

3 x + 4 x + 5 x + 6 x= $360^{\circ}$

$\Rightarrow 18 x=360^{\circ}$

$\Rightarrow x= 20^{\circ}$

$\therefore$ Smallest angle of the triangle

= $3\times 20\times \frac{2}{3}$

= $40^{\circ}$

$\therefore$ Largest angle of the triangle

= $40^{\circ}\times$ 2

= $80^{\circ}$

$\therefore$ Second largest angle of the triangle

= $180^{\circ}-(40^{\circ}+80^{\circ})$

= $60^{\circ}$

and the largest angle of the quadrilateral

=6 x

= $6\times 20^{\circ}$

=120 $^{\circ}$

Hence, required sum

= $60^{\circ}$ + $12^{\circ}$

= $180^{\circ}$

Incorrect

Let the angles of the quadrilateral be 3 x,4 x,5 x and 6 x respectively.
Then,

3 x + 4 x + 5 x + 6 x= $360^{\circ}$

$\Rightarrow 18 x=360^{\circ}$

$\Rightarrow x= 20^{\circ}$

$\therefore$ Smallest angle of the triangle

= $3\times 20\times \frac{2}{3}$

= $40^{\circ}$

$\therefore$ Largest angle of the triangle

= $40^{\circ}\times$ 2

= $80^{\circ}$

$\therefore$ Second largest angle of the triangle

= $180^{\circ}-(40^{\circ}+80^{\circ})$

= $60^{\circ}$

and the largest angle of the quadrilateral

=6 x

= $6\times 20^{\circ}$

A 320 m long train moving with an average speed of 120 km/h crosses a platform in 24 s. A man crosses the same platform in 4 min. What is the speed of man in m/s?
- 2.4
- 1.5
- 1.6
- 2.0
- None of these
Correct

Speed of train

= 120 km/h

= $120\times \frac{5}{18}$ m/s

= $\frac{100}{3}$

Suppose the length of the platform = x m
Then,

$\frac{x+320}{100}$ =24

$\Rightarrow 3(x+320)=100\times 24$

$\Rightarrow$ x+320=800

$\Rightarrow$ x=800-320=480 m

Hence, speed of man

= $\frac{480}{4\times 60 }$ m/s

=2 m/s

Incorrect

Speed of train

= 120 km/h

= $120\times \frac{5}{18}$ m/s

= $\frac{100}{3}$

Suppose the length of the platform = x m
Then,

$\frac{x+320}{100}$ =24

$\Rightarrow 3(x+320)=100\times 24$

$\Rightarrow$ x+320=800

The simple interest accrued on a sum of certain principal is Rs. 7200 in six years at the rate of 12 p.c.p.a. What would be the compound interest accrued on that principal at the
rate of 5 p.c.p.a. in 2 yr?
- Rs.1020
- Rs.1055
- Rs.1050
- Rs.1025
- None of these
Correct

Suppose the principal amount= Rs.x

Then,

7200= $\frac{x\times 12\times 6}{100}$

$\Rightarrow x=\frac{7200\times 100}{12\times 6}$

$\Rightarrow$ x=Rs.10000

$\therefore$ amount interest

= $10000(1+\frac{5}{100})^{2}-10000$

= $10000(\frac{21}{20})^{2}-10000$

= $10000\times \frac{441}{400}-10000$

= $\frac{410000-4000000}{400}$

= $\frac{410000}{400}$

= Rs.1025.

Incorrect

Suppose the principal amount= Rs.x

Then,

7200= $\frac{x\times 12\times 6}{100}$

$\Rightarrow x=\frac{7200\times 100}{12\times 6}$

$\Rightarrow$ x=Rs.10000

$\therefore$ amount interest

= $10000(1+\frac{5}{100})^{2}-10000$

= $10000(\frac{21}{20})^{2}-10000$

= $10000\times \frac{441}{400}-10000$

first number? (assuming both the numbers are positive)
- 18
- 8
- 9
- 16
- None of these
Correct

Suppose the first number=x

and second number=y

Then,

$8^{2}-y^{2}=15$

$\Rightarrow 64-y^{2}=15$

$\Rightarrow y^{2}=49$

$\Rightarrow y=\sqrt{49}=7$

Again,

$x^{2}+y^{3}=568$

$\Rightarrow x^{2}+7^{3}=568(on putting value y=7)$

$\Rightarrow x^{2}+343=568$

$\Rightarrow x^{2}=225$

$\Rightarrow x=\sqrt{225}=15$

Hence, three fifth of the first number

= $\frac{3}{5}\times 15$

=9.

Incorrect

Suppose the first number=x

Then,

x+(x+2)+(x+6)+(x+8)+(x+10)+(x+12)+(x+14)=656

$\Rightarrow$ 8 x+56=656

$\Rightarrow x=\frac{600}{8}$ =75

Let the four consecutive even numbers be

x,x+2,x+4,x+6,x+8,x+10,x+12,x,x+2,x+4 and x+6 respectively.
