Question

I have total 300 coins of denomination 1,2 and <5. The
number of 2 coins is three times the number 5 coins. The
total number of coins is 100. How many coins of each
denominations are with me?​

Answer 1

Answer:

Number of coin of 5 = 20 coins

Number of coin of 2 = 60 coins

Number of coin of 1 = 80 coins

Step - by - step explaination:

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

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
