Question

If 42 men can dig a trench in 14 days, then 1 men can dig it in
__________ days.

Answer 1

men and days are inversely proportional

so

m1*d1 = m2*d2

m1 =42, d1=14

m2 =1, d=?

42×14 = 1× d

d = 588

1 man takes 588 days to dig

Answer 2

Let 1 men can dig trench in x days

Therefore = 42men × 1 men = 14days × x

=42men/14days = x days

x days = 3men/1 days

x= 3men
