Answer:
Step-by-step explanation:
do part of park in 1 day=1/80
Work done by ajay in 10 days=10/80
=1/8
Remaining work=1-1/8
=7/8
B complete in 42 days=7/8part of work
B can complete in1day=1/48part of work
So B alone can complete it in 48 days
Work done by both in 1 day
=1/80+1/48
=(3+5)/240
=1/30
So they can finish the work together in 30days
