A bag contains 5ps coins, 10ps coins and 20ps coins in the ratio of 3:2:1. If their total value is Rs. 11 what is the number of 5ps coins?
Read Solution (Total 2)
-
- coins are in ratio 3:2:1
->5 paise coins=3*X*5/100(as the coins are not in rupee value so convert it into rupee)
->10 paise coins=2*x*10/100
->20 paise coins=1*x*20/100
adding these we get-> 11*x/20=11
->x=20
->20 paise coins=20
->10 paise=40
->5 paise =60 - 11 years agoHelpfull: Yes(6) No(0)
- since 5:10:20=1:2:4 nd coiins in the ratio 3:2:1 so total values are in the ratio of product of these two..3:4:4=11
so value of 5 paise coin =3
so there are 60n coins of 5 paise..
