A bag contains 3,150 coins. There are 1 rupee coins, 2 rupee coins and 5 rupee coins in the bag. The ratio of each coin is 3:2:5 respectively. Then calculate the number of each coin.
Sum of ratio =3+2+5=10
Total coins =3,150
∴ No. of 1Re. coins =310×3,150=945
No. of 2Rs. coins=210×3,150=630
No. of 5Rs. coins=510×3,150=1,575.
