**Infosys Aptitude Interview Questions & Answers**

1) X fires 5 shots to Y’s 3, but X kills only once in 3 shots while Y kills once in 2 shots. When Y has missed 27 times, X has killed:

- 30 birds
- 60 birds
- 72 birds
- 90 birds

**Answer:** 1

**Solution:**

Let the total fires y. Then,

Shots fired by X = 5 y

8

Shots fired by Y = 3 y

8

Killing shots by X = 1 of 5 y = 5 y

3 8 24

Shots missed by Y = 1 of 3 y = 3 y

2 8 16

3x = 27 or y = 27 x 16 = 144.

16 3

Birds killed by X = 5y = 5 x 144 = 30.

2) Gaurav’s age after 15 years will be 5 times his age 5 years back. What is the present age of Gaurav?

- 10 years
- 18 years
- 20 years
- Cannot be determined
- None of these

**Answer:** 1

**Solution:** Let Gaurav’s present age be x years. Then, Gaurav’s age after 15 years = (x + 15) years. Gaurav’s age 5 years back = (x – 5) years. Therefore x + 15 = 5 (x – 5) x + 15 = 5x – 25 4x = 40 x = 10. Hence, Gaurav’s present age = 10 years.

3) The statement I: The government has recently fixed the fees for professional courses, which are much lower than the fees charged in the last year offered by the unaided institutions

Statement 2: The parents of the students launched a severe agitation last year protesting against the high fees charged by the unaided institutions.

- The statement First is the cause and statement Second is its effect
- Statement Second is the cause and statement First is its effect
- Both the statements First and Second are independent causes
- Both the statements First and Second are effects of independent causes

**Answer:** 2

**Solution:** Because the parents of the students launched a serve agitation last year protesting against the high fees charged by the unaided institutions, the government has recently fixed the fees for professional courses. Hence option 2 is correct.

4) A is as much younger than B. B as he is older than C. If the sum of the ages is 50 years. What is the difference between the ages of B and A’s?

- 1 year
- 2 years
- 25 years
- Data inadequate
- None of these

**Answer:** 4

**Solution:** Given that:

1. The difference of age b/w B and A = The difference of age b/w A and C.

2. Sum of age of B and C is 50 i.e. (B + C) = 50.

Question: B – A = ?.

**Explanation:**

B – A = A – C

(B + C) = 2A

Now given that, (B + C) = 50

So, 50 = 2A and therefore A = 25.

Question is (B – A) = ?

Here we know the value(age) of A (25), but we don’t know the age of B.

Therefore, (B-A) cannot be determined.
