Question

Rahul has 260 coins of rs. 1,2 and 5. The total value of money if rs 300. The no. of rs 2 coins is three times that of rs. 5 coins. Find the no. Of each type of coin

Answer 1

Answer :

coin of 5 = 20 coins

coin of 2 = 60 coins

coin of 1 = 80 coins

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 5 = 20 coins so the number of coin of 2 = 60 coins

so the number of coin of 5 = 20 coins so the number of coin of 2 = 60 coinsso the number of coin of 1 = 80 coins

Answer 2

Hey mate,.

Let be the number of 5 rupees cions = Rs.x

let the number of 2rupees cions = 3x

let the number of 1 rupees coins = 160 - 4x

then total amount of 5 rupees coins = 5x

then the amount of 2 rupees coins = 6x

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

7x = 300 - 160

7x = 140

x = 20

There fore,

the cost of 5 rupees coins =20

the cost of 2 rupees coins =60

the cost of 1 rupees coins=80

Hope it will help you
