Question

3. A and B complete a piece of work in 10 and 14 days respectively. A and B work
together for 3 days and then leaves. How much time will B take to complete the remaining
work?​

Answer 1

Answer:

tigether work completed in 1 day =1/10+1/14=12/70=6/35 work

so work completed in 3 days=18/35

work remaining 1-18/35=17/35

b completes 1/10 work in 1 day

so he will complete 17/35 work in 170/35 days or 4.9 days or 5 days
