A's 1 day work = 1/30
A's 5 day work = 5 * 1/30 = 1/6

Remaining work = 1-1/6 == 5/6

B done 5/6 of work in 20 days

Then B ll finish the whole work in
6/5 * 20 == 24 days

A ll finish d work in 30 days
B ll finish d work in 24 days

A + B's 1 day work is
1/30 + 1/24 = 54/720 = 3/40

A + B together ll finish in 40/3 days
