In a row of boys, Aman is fifteenth from the left end and Dhanush is eighteenth from the right end. If in this row Aman is eleventh from the right end, then what is the position of Dhanush from the left end?
When a person's position is known from both ends, Total strength = position from left + position from right - 1.
To convert a position from one end to the other end, use: position from left = Total - position from right + 1.
Step 1: Find the total number of boys using Aman's two given positions.
Aman is 15th from the left end and 11th from the right end.
Total = 15 + 11 - 1 = 25 boys in the row.
Step 2: Convert Dhanush's position from the right end to the left end.
Dhanush is 18th from the right end.
Position from left = 25 - 18 + 1 = 8.
Step 3: Verify the answer.
Check: 8th from left + 18th from right - 1 = 8 + 18 - 1 = 25, which matches the total strength found in Step 1.
Final Answer: Dhanush is Eighth from the left end (option 2)
