Explanation

Let's denote A's rate of work as A, and B's rate of work as B.

Given A + B together complete the work in 12 days:

(A + B)'s 1 day's work = 1/12

B alone completes the work in 20 days:

B's 1 day's work = 1/20

A's 1 day's work = (A + B)'s 1 day's work - B's 1 day's work

= 1/12 - 1/20

= (5 - 3) / 60

= 2 / 60

= 1 / 30

A alone will complete the work in 30 days.

Explanation

Given:

Average = 18

Numbers: 7, 13, 17, x, 29

Average = (Sum of numbers) / (Total count)

18 = (7 + 13 + 17 + x + 29) / 5

Multiply both sides by 5:

90 = 66 + x

x = 90 - 66

x = 24
