Correct Answer: 18th
Solution :
Given:
In a row of girls, Kamala is tenth from the left and Vimala is twelfth from the right. When they exchange their places, Kamala is sixteenth from the left.
Position of Kamala from left end = 10
Position of Vimala from right end = 12
After interchanging positions, Kamala's position from the left = 16
New position of Vimala from right end = (Kamala's new position from left – Kamala's old position from left) + Vimala's old position from right end
= (16 – 10) + 12
= 6 + 12
= 18
So, Vimala is in the 18th position from the right end. Hence, the first option is correct.
