Question

I have a total of Rs 300 in coins of denomination Rs 1, Rs 2 and Rs 5. The number of Rs 2 coins is 3 time the number of Rs 5 coins. The total number of coin is 160. How many coins each denomination are with me?​

Answer 1

Step-by-step explanation:

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

Answer 2

Answer:

The number of coin of 5 = 20 coins

The number of coin of 2 = 60 coins

The number of coin of 1 = 80 coins
