Question are bit easy.
50 question of Time, Speed, Percentage and 10 question on C basic mcq.

1. Aptitude Question

A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.

Problem approach

Speed downstream = (13 + 4) km/hr = 17 km/hr.

Time taken to travel 68 km downstream = 68/17 hrs = 4 hrs

You are given an array Arr consisting of n integers, you need to find all the distinct triplets present in the array which adds up to zero.

An array is said to have a triplet {arr[i], arr[j], arr[k]} with 0 sum if there exists three indices i, j and k such that i!=j, j!=k and i!=k and arr[i] + arr[j] + arr[k] = 0.

Note :
1. You can return the list of values in any order. For example, if a valid triplet is {1, 2, -3}, then (2, -3, 1), (-3, 2, 1) etc is also valid triplet. Also, the ordering of different triplets can be random i.e if there are more than one valid triplets, you can return them in any order.
2. The elements in the array need not be distinct.
3. If no such triplet is present in the array, then return an empty list, and the output printed for such a test case will be "-1".
Problem approach

Run three loops and check one by one whether the sum of the three elements is zero or not. If the sum of three elements is zero then print elements otherwise print not found.

3. Output Question

Predict the output of the following pseudo-code if x= 1 and y=2: Integer solve(int x, int y) if(x > 1)   solve(x – 1, y + 3) end if print y End function solve()A) 2B) 3C) 6D) 4

Problem approach

Ans:- 2

4. Output Question

What is the output?#includeint main() {    typedef int num;    num bunk = 0.00;        printf("%d", bunk);    return 0;    }A) Zero B) 0.0C) Garbage Value

Problem approach

Integer part of 0.00 is equal to 0.
Hence only zero will be printed with printf("%d", bunk), when 0.00 is passed, because %d stands for integer.

5. Maths Question

What is the compound interest on Rs. 2500 for 2 years at rate of interest 4% per annum?

Rs. 180
Rs. 204
Rs. 210
Rs. 220

Problem approach

The Correct answer is (B) :- 204

Explanation:

Principal (P) = Rs. 2500

Rate of interest(r) = 4%

Time (t) = 2 years

Compound Interest = Amount ? Principal

Amount(A)=P

6. OS Question

What is virtual Memory?

7. DS Question

How is the 3rd element in an array accessed based on pointer notation?

Problem approach

a[3] in C is equivalent to *(a + 3) in pointer notation.

8. Output Question

Which of the following series will be printed by the given pseudocode? Integer a, b, c Set b = 4, c = 5 for(each a from 2 to 4)   print c   b = b - 1   c = c + b end forA) 5 8 10B)1 3 6C) 8 9 10

Problem approach

Firstly variables a, b, and c are initialized, then b and c are assigned values 4 and 5 respectively. 
Now run a loop from 2 to 4, in each iteration b is decremented by 1, and c is incremented by b. 
In the first iteration print c = 5 value of b is decremented by 1 i.e. b = 3, c is incremented by b i.e. c = 5 
In the second iteration print c = 8 value of b is decremented by 1 i.e. b = 2, c is incremented by b i.e. c = 8 
In the third iteration print c = 10 value of b is decremented by 1 i.e. b = 1, c is incremented by b i.e. c = 10 

Thus the final series is 5, 8, 10
