Question

Potty to worker after working 8 hour Per day constructed a wall in 15 days. In how many days 40 workers after working 9 hours can complete the the same work?

Answer 1

Answer:

Step-by-step explanation:

(M1*D1*H1)/(W1*R1) = (M2*D2*H2)/(W2*R2)

Here, M represents the Number of people (Can be Men, Women, Children or a combination of all)

D represents the Number of days worked

H represents the number of hours

W represents the amount of work

R represents the revenue or the money that is earned.

So for your question, M1 = 20, D1 = 15, H1 = 8

M2 = 12, D2 = 10

Since the amount of work done is the same, W1 = W2, and since the revenue is not mentioned R1 and R2 can be taken as 1.

Substituting the above values in the formula, we get

H2 = 20 hours.
