A . 80

B . 40

C . 32

D . 72

Answer : B . 40

Explanation :

    • c = ?
    • d = 2
    • c = a * d + b
    • c = a * 2 + b then a = 5 b = 20
    • c = ?
    • c = c + d
    • c = a * 2 + b + d
    c = 5 * 2 + 20 + 10 = 40

Ravi and Rupali are asked to write a program to sum the rows of 2X2 matrices stored in the array A.
Ravi writes the following code (Code A):

 for n = 0 to 1 
 sumRow1[n] = A[n][1] + A[n][2]
 end

Rupali writes the following code (Code B):

sumRow1[0] = A[0][1] + A[0][2] 
sumRow1[1] = A[1][1] + A[1][2]

Comment upon these codes (Assume no loop unrolling done by compiler) ?

A. Code a will execute faster than b.

B. Code b will execute faster than a.

C. Code a is logically incorrect.

D. Code b is logically incorrect

Answer : B. Code b will execute faster than a

Explanation:

  • Both codes are taking two steps of operation, so same complexity.
  • But if we consider the overhead of looping (as it takes time to increment counter) then code b will be faster.

The construct “if (condition) then A else B” is used for which of the following purposes ?

A. Decision making

B. Iteration

C. Recursion

D. Object oriented programming

Answer : A. Decision making

Explanation:

If-Else for Decision Making:

  • The if statement alone tells us that if a condition is true it will execute a block of statements and if the condition is false it won’t. But what if we want to do something else if the condition is false. Here comes the else statement. We can use the else statement with if statement to execute a block of code when the condition is false.

Ashima wants to print a pattern which includes checking and changing a variables value iteratively She decides to use a loop/condition Which of the following options should she use such that the body of the loop/condition is executed at least once whether the variable satisfies the entering condition or not ?

A. For loop

B. While loop

C. Do-while loop

D. Switch case

E. None of these

Answer : C. Do-while loop

Explanation:

Do While Loop :

  • Unlike for and while loops, which test the loop condition at the top of the loop, the do…while loop in C programming checks its condition at the bottom of the loop.
  • A do…while loop is similar to a while loop, except the fact that it is guaranteed to execute at least one time.

Syntax for Do While Loop :

do {
     statement(s);
}    while( condition );

A. 980

B. 797

Answer : B. 797

Explanation:

  • If we remove the remainder from number, 5678-35 = 5643
  • 5643 should be divisible by 460, means the unit digit must be 5 if we add any number from options.
  • The only number 797 can give the unit digit 5, So answer is 797.

A number is divided by 5, 3, 2 successively in order to get remainders of 0, 2, 1 respectively. What will be the remainder when the same number is divided by 2, 3, 5 respectively ?

A. 4, 3, 2

B. 1, 0, 4

C. 2, 1, 3

D. 4, 1, 2

Answer : B. 1, 0, 4…

Explanation:

Let the number = N.
Now N = 5K
K = 3L + 2
L = 2M + 1
K = 3 (2M + 1) + 2
= 6M + 5
N = 5 (6M + 5)
= 30 M + 25.

For M = 0 we get the least number as 25. Now when 25 is divided by 2, we get 12 as quotient and 1 as remainder.
When 12 is divided by 3 we get 4 as quotient, and 0 as remainder. When 4 is divided by 5 we get 4 as remainder.

What is the chance that a leap year selected at random contains 53 Fridays ?

A. 1/7

B. 3/7

C. 2/7

D. 2/13

Answer : C. 2/7

Explanation:

  • A leap year there are 366 days means 52 weeks and 2 days. so already we have 52 fridays.
  • Now the rest two days can be (sun, mon), (mon,tues), (tues, wed), (wed, thrus), (thrus, fri), (fri, sat), (sat, sun) so, the probability of 53 fridays = 2/7.
