Given information:
- Amar is 16th from the left end.
- Vishal is 18th from the right end.
- Ganesh is 11th from Amar towards the right.
- Ganesh is 3rd from Vishal towards the right end.
To find: How many boys are there in the row?
Solution:
1. Let's first find the position of Ganesh from the left end of the row.
- We know that Ganesh is 11th from Amar towards the right.
- So, the position of Amar from the right end can be calculated as: Total number of boys - 16 + 1 (including Amar himself) = Total number of boys - 15.
- Hence, the position of Ganesh from the left end can be calculated as: Total number of boys - 15 - 11 + 1 (including Ganesh himself) = Total number of boys - 24.
2. Now, we can use the second piece of information to find the position of Ganesh from the left end.
- We know that Ganesh is 3rd from Vishal towards the right end.
- So, the position of Vishal from the left end can be calculated as: Total number of boys - 18 + 1 (including Vishal himself) = Total number of boys - 17.
- Hence, the position of Ganesh from the left end can be calculated as: Total number of boys - 17 - 3 + 1 (including Ganesh himself) = Total number of boys - 19.
3. Equating the two expressions we got for the position of Ganesh from the left end, we get:
Total number of boys - 24 = Total number of boys - 19.
Solving this equation, we get:
Total number of boys = 41.
Therefore, there are 41 boys in the row. Hence, option D is the correct answer.
