In a row of girls, Shilpa is eight from the left and Reena is seventeenth from the right. If they interchange their positions, Shilpa becomes fourteenth from the left. How many girls are there in the row?

A31

B30

C29

D28

Answer:

B. 30

Read Explanation:

Shilpa is eight from the left and Reena is seventeenth from the right. Since Shilpa and Reena interchange positions, so Shilpa's new position is the same as Reena's earlier position. Shilpa's new position is 14th from the left and 17th from the right. Total number of girls in the row = 14 + 17 - 1 = 31 - 1 =30
