Explanation

Let's denote the number of coins as 2x, 3x, and 4x for Rs 2, Rs 5, and Rs 10 coins, respectively.

The total value is:

2(2x) + 5(3x) + 10(4x) = 472

4x + 15x + 40x = 472

59x = 472

x = 8

Number of Rs 2 coins = 2x = 2(8) = 16

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.
