Answer 1

49-17 = 32
32-7 = 25
49-25 = 24

answer: (2) 24th

Answer 2

Sumit's rank is seventeenth from the last

⇒ There are 16 people behind him

Rajesh is 7 ranks ahead of Sumit

⇒ There are 6 people between Rajesh and Sumit

The end of the queue goes this way :

⇒Rajesh + 6 people + Sumit + 16 people

⇒ 1 + 6 + 1 + 16 = 24 people

Number of people infront of Rajesh:

49 - 24 = 25

There are 25 people in front of rajesh

⇒ Rajesh is in the 26th position from the start

Answer: (3) 26th
