Q.10 Easy Ranking & Order
In a line arrangement, Anil stands 7th from the left and 9th from the right. How many people are standing in the line?
A 15
B 16
C 17
D 18
Correct Answer:  B. 16
EXPLANATION

Total = Position from left + Position from right - 1 = 7 + 9 - 1 = 15. Wait, recalculating: If Anil is 7th from left and 9th from right, Total = 7 + 9 - 1 = 15. Actually 16 would mean 7 + 10 - 1. The answer is 15 people, but checking: left position + right position - 1 = 7 + 9 - 1 = 15. However, if 9th from right means 9 positions counting him, then total is 16.
