60people can do a work in 20days
one people fo this work in =60*20=120
40 man can complete this work in =120/40=3days
one people fo this work in =60*20=120
40 man can complete this work in =120/40=3days
Let M1= first worker
Let d1 = first time
Let M2 = after time
Let d2= after time
M2 = after workers
D2 = M1*d1 ÷ M2
D2 = 60*20÷ 40
D2 = 60*20÷ 40
D2 = 30 days
why are you select my answer
