Question

In a class of 45 students, a boy is ranked 20^th. When two boys joined, his rank was dropped by one. What is his new rank from the end?

(a) 25^th (b) 26^th (c) 27^th (d) 28^th

Answer 1

(c) Initial strength of class = 45

Now, new strength = 47

The boy’s rank is dropped by one Now, his rank becomes 21.

Total number of boys in class = Boy’s rank from starting + Boy’s rank from end – 1

∴ Boy’s rank from end = 47 – 21 + 1 = 27
