Question

11. If 12 men or 18 women can complete a piece
of work in 7 days, in how many days can 4 men
and 8 women complete the same work?​

Answer 1

Answer:

5 days

Step-by-step explanation:

12 men = 7 days

then 1 men = 7/12

i.e 0.5833

also 18 women = 7 days

then 1 women =7/18

i.e 0.38888

therefore 4M+8W = 4(0.5833)+8(0.3888)

2.3332+3.1104

i.e 5.4436

therefore 5 days they need to complete the same work
