A's 1 day's work = 1/10
and B's 1 day's work = 1/15.
(A+B)'s 1 day's work = (1/10+1/15)
= 1/6.

A's 1 day's work = 1/15
B's 1 day's work = 1/20
(A+B)'s 1 day's work = (1/15 + 1/20)
= 7/60.
(A+B)'s 4 day's work = (7/60x4)
= 7/15.
Remaining Work = (1–7/15)
= 8/15.

A's 1 day's work = x
B's 1 day's work = y
Then, x+y = 1/30 and 16x+44y = 1.
Solving these two equations, we get x=1/10 and y=1/60
Therefore B's 1 day's work= 1/60.
