Step-by-step explanation:
No.of days taken by Sam to do the work=10
Work done by Sam in 1 day=1/10
No.of days taken by John to do the work=20
Work done by John in 1 day=1/20
So,
Work done by both of them in 1 day=1/10+1/20
=(1+1)/20
=2/20
=1/10
Therefore,
No.of days taken to do the whole work=1/(1/10)
=1×10
= 10 days..
