Let's break it down step by step; shall we💁🏾♂️
So:-
- 25 bricklayers lay 25,000 blocks in 5 days.
- To find the total work done, multiply the number of bricklayers by the number of days: 25 bricklayers x 5 days = 125 bricklayer-days.
- Since they laid 25,000 blocks in 125 bricklayer-days, the rate of work is: 25,000 blocks / 125 bricklayer-days = 200 blocks per bricklayer-day.
- Now, we need to find out how many bricklayer-days are required to lay 32,000 blocks: 32,000 blocks / 200 blocks per bricklayer-day = 160 bricklayer-days.
- Finally, since there are 40 bricklayers, we divide the total bricklayer-days by the number of bricklayers: 160 bricklayer-days / 40 bricklayers = 4 days.
Therefore, 40 bricklayers will take 4 days to lay 32,000 blocks.
The answer is 4 (B)
