Question

If 12 labour can earn rs 12240 in 12 days. How many labours can earn rs 6800 in 8 days?

Answer 1

no of labours days = 12*12= 144
wage of each labour day= 12240/144= 85
labour days required to earn 6800 = 6800/85= 80
no of labours = 80/ 8= 10 labours

Answer 2

Answer:

First we have to find wages for work done by one man in one day.

12 man in 12 days gets 12240.

So 1 man in 1 day = 12240/(12*12)=85

Now “N” men in 8 days = N*85*8 which is given as 6800.

N=6800/(85*8)

N=10
