Question 1: Sushil was thrice as old as Snehal 6 years back. Sushil will be times as old as Snehal 6 years hence. How old is Snehal today? [Bank P.O. 1992]

Options
(a) 18 years
(b) 12 years
(c) 22 years
(d) 24 years

Answer: Let Snehals age 6 years back = x.

Then, Sushils age 6 years back = 3x.

$\left ( \frac{5}{3} \right )$ Χ (x + 6 + 6) = (3x + 6 + 6) hence 5(x+ 12) = 3(3x+ 12) so x=6.

Snehal today = (x+ 6) years = 12 years.

Question 2: A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train?

Options
(a) 230 m
(b) 260 m
(c) 240 m
(d) 270 m

Answer: Relative speed = (120 + 80) km/hr

$\left ( 200\times \frac{5}{18} \right )m/sec$

$\left (\frac{500}{9}\right )m/sec$

Let the length of the other train be x metres.

Then, $\frac{x+270}{9}=\frac{500}{9}$

x+ 270 = 500

x = 230.

Question 3: When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?

Options
(a) Rs. 21,000
(b) Rs. 22,500
(c) Rs. 25,300
(d) Rs. 25,800

Answer: 85 : 18700 = 115 : x

x = 18700 x 115 = 25300.

Hence, S.P. = Rs. 25,300

Question 4: The discount on a bill due 9 months hence a 16% per annum is Rs.189 The amount of the bill is :

Options
(a) Rs.1468
(b) Rs.1764
(c) Rs.1575
(d) Rs.2356

Answer: Let P.W. be RS. x. Then,S.I. on Rs. x at 16% for 9 months=Rs.189.

$\therefore$ x$\times 16\times \frac{9}{12}\times \frac{1}{100}=189 or x =1575$

$\therefore$ P.W.=Rs.1575.

$\therefore$ Sum due = P.W.+T.D==Rs.(1575+189)=Rs.1764 .

Question 5: Two dice are thrown simultaneously. What is the probability of getting two numbers whose product is even? (S.B.I. 2000)

Options
(a) $\frac{3}{4}$
(b) $\frac{2}{4}$
(c) $\frac{3}{2}$
(d) None of these

Answer: n(S) = (6 x 6) = 36.

Then, E = {(1, 2), (1, 4), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 2), (3, 4),
(3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 2), (5, 4), (5, 6), (6, 1),
(6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

n(E) = 27.

$\therefore p(E)=\frac{N(E)}{N(S)}=\frac{27}{36}=\frac{3}{4}$

Question 6: The third proportional to 0.36 and 0.48 is :

Options
(a) 0.64
(b) 0.1728
(c) 0.42
(d) 0.94

Answer: Let the third proportional to 0.36 and 0.48 be x

Then, 0.36 : 0.48 : 0.48 : x

$\Rightarrow \left ( \frac{0.48\times 0.48}{0.36} \right )=0.64$

Question 7: The cost of 15 Bags of salt, each weighing 915 grams is Rs. 18. What will be the cost of 25 Bags, if each bag weight is 1 kg?

Options
(a) 32.78
(b) 46.64
(c) 53.3
(d) 34.23

Answer: More bags, More cost

More weight, More cost

Bags 15 : 25 } :: 18 : z

Weighing 915 : 1000

Therefore, (15 x 915 x z) = (25 x 1000 x 18) So, the Rs. is 32.78.

Question 8: Tea worth Rs. 126 per kg and Rs. 135 per kg are mixed with a third variety in the ratio 1 : 1 : 2. If the mixture is worth Rs. 153 per kg, the price of the third variety per kg will be: (bank p.o 2002)

Options
(a) 145.50
(b) 165.70
(c) 175.50
(d) None of these

Answer: Since first and second varieties are mixed in equal proportions.

So, their average price = Rs.$(\frac{126+135}{2})$

So, the mixture is formed by mixing two varieties, one at Rs. 130.50 per kg and the other at say, Rs. x per kg in the ratio 2 : 2, i.e., 1 : 1. We have to find x.

By the rule of alligation, we have:

$\therefore \frac{x-153}{22.50}=\: 1\Rightarrow x - 153 = 22.50$

x = 175.50

Question 9: Which of the following number divides the product of 8 consecutive integers?

Options
(a) 4!
(b) 8!
(c) 6!
(d) 7!

Answer: 8! = $8\times 7\times 6\times 5\times 4\times 3\times 2\times 1$

so 8! is divisible by 8 consecutive number

Question 10: From a point P on a level ground, the angle of elevation of the top tower is 30º. If the tower is 100 m high, the distance of point P from the foot of the tower is: (bank p.o 1999)

Options
(a) 100 m
(b) 150 m
(c) 173 m
(d) 200 m

Answer: Let AB be the tower.

Then , $\angle APB=30^{\circ}$ and AB = 100 m

$\Rightarrow AP=(AB\times \sqrt{3})m$

= $100\sqrt{3}m$

= (100 x 1.73) m
= 173 m.
