Answer:
Step-by-step explanation:
Since Vikram and Vinay can do a work in 20 days together
So their one day work = 1/20
Vinay can do the whole work alone in 30 days
so Vinay's one day work = 1/30
They worked together for 8 days so
work done by them in 8 days = 1/20* 8
= 2/5 unit
remaining work = 1 - 2/5 = 3/5
Remaining work done by Vinay = Remaining work/efficiency
= 3/5÷1/30
= 3/5*30
= 18 days
