Question

A purse has only two rupee and five rupee coins. The sum of the coins is 36 and the total value of the coins is Rs. 84. Find the number of five rupee coins.

Answer 1

number of 2 rupee coin = 32

and

number of 5 rupee coin = 4

total coin = 32+4=36

total value of coin = (2*32) + (5*4)
= 64 + 20 = 84

so

the number of 5 rupee coin = "4"
