There are 40 benches in a single row from west to east in a park. A green bench is 13th from the west end. A blue bench is the 8th bench to the east of the green bench. What is the position of the blue bench from the east end?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 20th
Find the blue bench’s place from the west end first, then use position from the east = total − position from the west + 1.
The green bench is 13th from the west
The blue bench is the 8th bench to the east of it: \(13+8=21\)st from the west
Blue bench from the east \(=40-21+1=20\)th
