Answer 1

Answer:

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.

Step-by-step explanation:

Let x be no. of two rupee coins and y be no. of five rupee coins.

                        3x=180−84
