If7 men can do a piece of work in 16 days. The number of days in which 4 men
do it are
(a) 24
(b)23
(c)28
(d) 25​

Answer 1

Step-by-step explanation:

by formula: M1D1H1/W1 = M2D2H2/W2

where, M= no. of men

D= no. of days

H= no. of hours

W= work

we get,

7×16 = D×4. (since work is same, so W=1)

D= 7×16/4

D= 28

Answer 2

Answer:

28

Step-by-step explanation:

1 man will complete the job in 7*16days.

So, 4 will do in

7*16/4

=28days.

Hence, option D is the correct answer.
