Question : Directions: In a row of people, Manu is 7th from the bottom end of the row. Shrey is 10 ranks above Manu. If Shrey is 8th from the top, then how many people are there in this row?
Option 1: 25
Option 2: 26
Option 3: 24
Option 4: 23
Correct Answer: 24
Solution :
Given:
Manu is 7th from the bottom end of the row. Shrey is 10 ranks above Manu and is 8th from the top.
The rank of Shrey from the top = 8
The rank of Shrey from the bottom = 10 + 7 = 17 ( Since Shrey is 10 ranks above Manu)
Total number of people in a row = Rank from top + Rank from bottom – 1
Total number of people in a row = 8 + 17 – 1 = 24
So, the total number of people in the row is 24. Hence, the third option is correct.
