Question

Madhura has a total of Rs. 500 coins of denominations 2,Rs. 5 and 10.
The number of 2 coins is 5 times the number of 10 coins. The total
number of coins is 130. How many coins of Rs. 5 are with her?​

Answer 1

Answer:

Let the number of coin 5 = Rs.x

so the number of coin 2 = 3x

so the number of coin 1 = 160 - 4x

so amount of rs.5 = 5x

so the amount of rs.2 = 6x

a/q

5x + 6x + 160 - 4x = 300

7x = 300 - 160

7x = 140

x = 20

so the number of coin of 5 = 20 coins

so the number of coin of 2 = 60 coins

so the number of coin of 1 = 80 coins
