Question

If a man complete a work in 2 months 10 days, how much time will be taken to complete the same work by 7 man?solution fast​

Answer 1

Answer:

2 months + 10 days => 30 + 31 + 10 = 71 days

work done by 1 man — 71 days

work done by 7 man — 71÷7 = 10.5 days

Answer 2

Answer:

10 days

Step-by-step explanation:

simply use unitary method,

work done by 1 man in 1 day = 1/2 months 10 days = 1/70

work done by 7 man in 1 day = (1/70)*7 = 1/10

now, we know 7 man do one tenth of the whole work in 1 day so to complete the whole work by 7 man = 10 days
