Question

Efficiencies of two men are in the ratio 2 : 3. If
the first takes 30 days to do a piece of work,
the time required when both of them work
together on a job twice as big as the first, will
be
30 days
18 days
24 days
72 days​

Answer 1

Step-by-step explanation:

capacity = 2 : 3

no. of days taken by first = 30 days

we have to find total work,

w = c * t = 2 * 30 = 60 total work

but if work is twice means = 120 total work

T = w/c = 120/5 = 24 days
