Question

In a row of children, Deepti is 9${}^{th}$ from the left and Kashish is 13${}^{th}$ from the right. They exchange their positions and then Deepti becomes 17${}^{th}$ from the left. What is the new position of Kashish from the right end of the row?

• A. 20^th
• B. 21^st
• C. 27^th
• D. 29^th
• E. None of these

Answer 1

The correct option is B

21^st

Deepti's new position is 17${}^{th}$ from the left and 13${}^{th}$ from the right.

So, no. of children in the row = 16+1+12 = 29

Now, Kashish's new position is Deepti's earlier position which is 9${}^{th}$ from the left.

No. of children to the right of Kashish = 29 - 9 = 20

Hence, Kashish's new position is 21${}^{st}$ from the right.
