Answer:
104 days
Step-by-step explanation:
200 men can finish a work in 150 days.After 20 days, 50 more men joined the work,
200 men* 150 days
250 men * 120 days
50 more men joined after 20 days,so 200 men worked for 20 days
200 men=20/150
200 men did in 2/15 days
remaining work,
1-2/15=13/15
13/15 work has to be done by 250 men in 120 days
(13/15)*120
13*8=104 days
