Question.  14

Number of whole numbers between 38 and 68 is

(A)

31

(B)

30

(C)

29

(D)

28

Detailed Answer with Explanation:

Step 1: “Between 38 and 68” means we do not include 38 and 68.

So we start from 39 and go up to 67.

Step 2: First number = \(39\)

Last number = \(67\)

Step 3: Use the counting formula:

\(\text{count} = \text{last} - \text{first} + 1\)

Step 4: Calculate:

\(67 - 39 = 28\)

\(28 + 1 = 29\)

Answer: There are \(29\) whole numbers. (Option C)
