Question

A job wear 20 people work 6 hours daily a work completed in 18 days if 15 people work in 12 days how many hour to complete a same work​

Answer 1

Answer:

Require 12 hour per day to complete a same work.

Step-by-step explanation:

given M1= 20, T1= 6, D1= 18,

M2= 15, T2 = ?, D1= 12,

here, W1= W2 (because same work)

W= M*T*D ------------(1)

W1= M1*T1*D1. W2= M2*T2*D2

put above value in equation (1)

M1*T1*D1=M2*T2*D2

20*6*18=15*T2*12

T2= 2160/180

T2= 12.

Require 12 hour per day to complete a same work.
