Question 1

One correct option

Assume that a, b, and c are three distinct integers. What will X represent after the execution of the following procedure?

Step 1. Maintain variable X and initialize it to 0

Step 2. If a < b then go to Step 4

Step 3. If b < c then store b in X else store c in X and stop the procedure.

Step 4. If a < c then store a in X else store c in X

A
Largest among a, b, and c
B
Smallest among a, b, and c
C
X will always be 0
D
Second smallest among a, b, and c

Question 2

1count = 0
2while(Table 1 has more rows){
3    Read the first row X from Table 1
4    C = 0
5    if(X.Mathematics > 75){
6        C = C + 1
7    }
8    if(X.Physics > 75){
9        C = C + 1
10    }
11    if(X.Chemistry > 75){
12        C = C + 1
13    }
14    if(C ≤ 2){
15        count = count + 1
16    }
