Model Test Paper - 3

Question 1: The total of the ages of A, B and C at present is 90 years. Ten years ago, the ratio of their ages was 1: 2: 3. What is the age of B at present? [Bank P.O. 1993]

(a) 40
(b) 20
(c) 30
(d) 18

Answer: Let their ages 10 years ago is x, 2x and 3x years.

10 + 2x + 10 + 3x + 10 = 90 hence x= 10

B’s present age = (2x + 10) =30 years.

Question 2: A 300 metre long train crosses a platform in 39 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform?

(a) 320 m
(b) 650 m
(c) 350 m
(d) Data inadequate

Answer: Speed=\left ( \frac{300}{18} \right )m/sec=\frac{50}{3}m/sec

Speed=\left ( \frac{300}{18} \right )m/sec=\frac{50}{3}m/sec

Then, \left ( \frac{x+300}{39} \right )=\frac{50}{3}

3x + 300 = 1950

x = 350 m.

Question 3: Nitesh goes to school from his village at the speed'of 4km/h and returns from school to village at the speed of 2 km/h. If he takes 6 h in all, then what is the distance between the village and the school?

(a) 6 km
(b) 5 km
(c) 4 km
(d) Cannot be determined
(e) None of these

Answer: Let the distance between the village.and school be x km.

\therefore \frac{x}{4} + \frac{x}{2} = 6

\frac{x+2x}{4}= 6

x = \frac{6 \times 4 }{3} = 8 km

Question 4: A man sold 250 chairs and had a gain equal to selling price of 50 chairs. His profit percent is.

(a) 5%
(b) 25%
(c) 10%
(d) 50%

Answer: sell price of 200 chairs = cost price of 250 chairs

let cost price of each chair is Rs 1

cost price of 200 chairs = 200

sell price of 200 chairs = 250

gain % = \left ( \frac{50}{200}\times 100 \right ) = 25%

(since; gain = sp of 250 chairs - cost price of 250chairs hence sp of 250 chairs - cost price of 250 chairs = SP of 50 chairs)

Question 5: The average of 5 consecutive even numbers A, B, C, D and E is 52. What is the product of B and E ?

(a) 2916
(b) 2988
(c) 3000
(d) 2800
(e) None of these

Answer: Let the five consecutive even numbers A, B, C, D and E

be x, x + 2, x + 4, x + 6 and x + 8, respectively.

now, \frac{x + (x + 2)+(x +4)+(x + 6)+ (x + 8)}{5}=52

\Rightarrow 5x + 20 = 260

\Rightarrow 5x = 240

\Rightarrow x = 48

\therefore B\times E=\left ( x+2 \right )\left ( x +8\right )=50\times 56=2800

Question 6: If three numbers in the ratio 3 : 2: 5 be such that the sum of their squares is 1862, the middle number will be:

(a) 7
(b) 21
(c) 14
(d) 35

Answer:Let the numbers be 3x, 2x and 5x. Then,

9x + 4x + 25x =1862 ⇒ 38x = 1862

x = 49

x = 7.
middle number = 2x = 14.

Question 7: A cistern has two taps which fill it in 24 minutes and 30 minutes respectively. There is also a waste pipe in the cistern. When all the three are opened, the empty cistern is full in 40 minutes. How long will the waste pipe take to empty the full cistern?

(a) 10 min
(b) 20 min
(c) 30 min
(d) 35 min

Answer: Work done by the waste pipe in 1 minute

\frac{1}{40}-(\frac{1}{24}+\frac{1}{30}) = \frac{1}{40}-\frac{9}{120} = \frac{1}{20}

Waste pipe will empty the full cistern in 20 minutes.

Question 8: In how many different ways can the letters of the word 'CLOUD' be arranged?

(a) 24
(b) 240
(c) 120
(d) 60
(e) None of these

Answer: The number of arrangement= 5!= 120

Question 9: The LCM of two numbers is 2079 and their HCF is 27. If one of the numbers is 297, find the other.

(a) 189
(b) 190
(c) 289
(d) 198
(e) None of these

Answer: We know,

HCF x LCM = one number X other number

\Rightarrow 27 x 2079 - 297 x other number

\Rightarrow Other number = 189

Question 10: Mahesh invested an amount of Rs. 12050 at simple interest. He got an amount of Rs. 13496 at the end of 2 yr. At what rate of interest did he invest?

(a) 12% per annum
(b) 8% per annum
(c) 6% per annum
(d) 4.5% per annum
(e) None of these

Answer: Let the rate of interest be r% per annum.

\therefore(13496 - 12050) =\frac{12050\times 2}{100}

\Rightarrow r =\frac{1446 \times100}{12050 \times 2}=6%\, \,per\, \,annum

Question 19: I felt the wall of the tunnel shiver. The master alarm squealed through my earphones. Almost simultaneously, Jack yelled down to me that there was a warning light on. Fleeting but spectacular sights snapped into ans out of view, the snow, the shower of debris, the moon, looming close and big, the dazzling sunshine for once unfiltered by layers of air. The last twelve hours before re-entry were particular bone-chilling. During this period, I had to go up in to command module. Even after the fiery re-entry splashing down in 81° water in south pacific, we could still see our frosty breath inside the command module.

Question 26: The neighborhood block association has received many complaints about people knocking on doors and soliciting money for an unknown charity organization even though door-to-door solicitation is prohibited by local laws. Three residents have provided descriptions of individuals who have come to their door asking for money.
Solicitor #1 is a white male, 20-25 years old, 5'9", 145 pounds, with very short brown hair. He was wearing a dark blue suit and carrying a brown leather briefcase.

Solicitor #3 is a white male, approximately 23 years old, 5'10", slight build, with short brown hair. He was wearing a blue suit.
Three days after the block association meet- ing, a resident noticed a man knocking on doors in the neighborhood and phoned the police to report the illegal activity. This solic- itor was described as follows:
Solicitor #4 is a white male, 22 years old, 140 pounds, about 5'10", with short brown hair. He was carrying a briefcase and wearing a dark suit.

Question 31: How do you access the values within an array?

Answer :Arrays contain a number of elements, depending on the size you gave it during variable declaration. Each element is assigned a number from 0 to number of elements-1. To assign or retrieve the value of a particular element, refer to the element number. For example: if you have a declaration that says “intscores[5];”, then you have 5 accessible elements, namely: scores[0], scores[1], scores[2], scores[3] and scores[4].

Question 32: Can I use “int” data type to store the value 32768? Why?

Answer :No. “int” data type is capable of storing values from -32768 to 32767. To store 32768, you can use “long int” instead. You can also use “unsigned int”, assuming you don’t intend to store negative values.

Question33: What are compound statements?

Answer : Compound statements are made up of two or more program statements that are executed together. This usually occurs while handling conditions wherein a series of statements are executed when a TRUE or FALSE is evaluated. Compound statements can also be executed within a loop. Curly brackets { } are placed before and after compound statements.

Question 34: What is || operator and how does it function in a program?

Answer :The || is also known as the OR operator in C programming. When using || to evaluate logical conditions, any condition that evaluates to TRUE will render the entire condition statement as TRUE.

Question35: What are linked list?

Answer :A linked list is composed of nodes that are connected with another. In C programming, linked lists are created using pointers. Using linked lists is one efficient way of utilizing memory for storage.
