In a row of children, Deepti is 9th from the left and Kashish is 13th from the right. They exchange their positions and then Deepti becomes 17th from the left. What is the new position of Kashish from the right end of the row?
Deepti's new position is 17th from the left and 13th 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 9th from the left.
No. of children to the right of Kashish = 29 - 9 = 20
Hence, Kashish's new position is 21st from the right.
