Answer 1

Answer:

Let the no of Rs 2 coins be x and the no of Rs 5 coins be y. So, the no of Rs 5 coins are 4.

Answer 2

Step-by-step explanation:

Let number of 2 rupees coins are x and 5 rupee are y.

x + y = 36 ... (i)

2x + 5y = 84 ... (ii)

(ii) - 2(i)

3y = 12

y = 4

x + y = 36

x + 4 = 36

x = 32

Hence, there are 32 two rupees coins and 4 five rupees coins.
