If 108 workers can build a wall in 36 days, then in how many days can 48 workers build the same wall?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 81.
Let the number of days required for 48 workers to build the wall be x .
According to the formula:
108 workers × 36 days = 48 workers × x days
⇒ 108 × 36 = 48 × x
⇒ x = (108 × 36) / 48
⇒ x = 3888 / 48
⇒ x = 81
