How many matrices of different orders are possible with elements comprising all prime numbers less than 30?

How many matrices of different orders are possible with elements comprising all prime numbers less than 30? Correct Answer 4

Concept:

Prime Numbers = a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11)

Calculation:

All prime numbers less than 30 = 2, 3, 5, 7, 11, 13, 17, 19, 23, 29

Total nos. of  elements = 10

Since matrices of different orders are possible with elements comprising all prime numbers less than 30.

In that case, total 4 matrices will be formed which will,

A =

B =

C =

D =

Hence Option 1 is correct.

Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory

A transporter receives the same number of orders each day. Currently, he has some pending orders (backlog) to be shipped. If he uses 7 trucks, then at the end of the 4th day he can clear all the orders. Alternatively, if he uses only 3 trucks, then all the orders are cleared at the end of the 10th day. What is the minimum number of trucks required so that there will be no pending order at the end of the 5th day?
