A group of men decided to do a job in 6 days, but 18 men dropped out every day. If the job was completed in 8 days, then how many men initially decided to do the job.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 252.
Let's assume the total number of men initially = x
So, the total work = 6x
18 men dropped out every day so the work done in 8 days
[x + (x - 18) + (x - 36) + (x - 54) + (x - 72) + (x - 90) + (x - 108) + (x - 126)] × 8 = 6x
8x - 504 = 6x
x = 252.
