Question

In a line of students, Rohan is 7th from the left and 20th from the right. How many students are there in the row?

A.

13

B.

14

C.

27

D.

26

Correct option is D

Given:
Rohan is 7th from the left.
Rohan is 20th from the right.
Total number of students = (Position from the left + Position from the right −1)
The total number of students in the row can be calculated by adding Rohan's positions from the left and the right, and then subtracting 1 (since Rohan is counted in both positions)
Total number of students = (7+20−1) = 26
Therefore, there are 26 students in the row.
Thus, correct answer is (d) 26
