Question

Sapna can type a manuscript in 8 days, while Barkha can do so in 10 days. They

started to type together but Sapna had to leave after 2 days. How many days will

Barkha take to complete the remaining work?​

Answer 1

Step-by-step explanation:

let the total work is 80

then the work efficiency of sapna=10 week/day

and the work efficiency of barkha= 8work/days

so,

both start together for two days

total worked of two days is 2(8+10)=36 work

remain work is (80-36)=44

remain work only do barkha so

taken time = 44/8=11/2 day. ans
