Question

if 30 wotkers can finish constructing a wall in 45 days. if the wall is contructed in 25 days. how many workers are needed

Answer 1

Answer:54 men

Step-by-step explanation:

Let total work = lcm of 30,45,25=1350

45 day ---------1350 work

1 day -----------1350/45=30 work

30 men------30 work

1 men---------1 work

According to question

We have to finish work in 25 days

=> To achieve this we have to do 1350/25 = 54 work per day.

1 men finish 1 work

So 54 men can finish 54 work in one day.

Ans :- 54
