Question

8 men compelet the sme work as 12 women .in how many days will 15 women compelet the same work which 12 men compelet the 20 day ?​

Answer 1

Step-by-step explanation:

12 men did the work in 24 day.

So 1 men will do this work in 12×24 =288 day.

8 men will do this work in 288/8=36day

8 men will do 1/36 of the work in 1 day.

Like this ; 15 women did the work in 24 day….1 women will take 15×24=360day. 8 women will do this work in 360/8=45day.

8 women will do 1/45 of the work in 1 day.

So 8 men & 8 women will do this work in 1 day=1/36+1/45=1/20 of the work.

8 men & 8 women will finish the work in 1÷1/20=1×20/1=20 days
