Aptitude Interview Questions and Answers

Two people on cycle are traveling at 10 miles / hour in opposite direction. When they are at a distance of 50 miles, a housefly lands on the first cyclist and then flies to the other at a speed of 16 miles/hour. What is the distance covered by fly?

You can assume that when the fly lands on cyclist 1 they are 50 miles apart. The fly has to travel 50 + x miles at 16 miles/hour. Here x is the additional distance at 10 miles/hour. So the problem is now simplified as
y = 50 + x (distance)
(50 + x)/16 = x/10 (time)
500 + 10x = 16x
6x = 500
x = 250/3 = 83.33
y = 133.33

When a number is multiplied by 13, it becomes greater to 105 by an amount with which it is lesser to 105 by now. What is the number

Author: Subhransu Sekhar Jena          Posted Date: November 21, 2014    Category: Aptitude     Points: 40

Let the number be x
105 - x = y
x = 105 - y
13x = 105 + y
14 x = 210
x = 15

A person has 14 red socks and 14 white socks in a drawer. What is the minimum number of socks that he should take to get a correct pair?

Author: Subhransu Sekhar Jena          Posted Date: November 21, 2014    Category: Aptitude     Points: 40

This is a classic probability puzzle and many puzzles are based on this logic. If the person picks up two socks then there is a possibility of them being different in colour. If he picks up three socks then they are guaranteed red or white. So the minimum number of socks required are three (3).

A person has certain number of cows and birds.they have 172 eyes and 344 legs.how many cows and birds does he have?

2. Each Cow has 2 eyes and 4 legs and each bird has 2 eyes and 2 legs. Lets call each eye as x and each leg as y. Also each bird is n and each cow is m so:
n(2x+2y) + m(2x + 4y) = 172x + 344y
2x (n+m) + 2y(n+2m) = 172x + 344y
(n+m) = 86 and (n+2m) = 172
n = 86 - m
86 - m + 2m = 172 or m = 86
This implies n = 0.
The owner has 0 birds and 86 cows.
