Solution

The correct option is C 150
There are 25 paise, 10 paise and 5 paise coins in a bag.
Their ratio is 1:2:3
Here total value is Rs. 30
Let exact quantity of coins be x,2x,3x respectively.
Then value of all coins combined =25x+10(2x)+(5)3x=60x paise
60x=30×100 paise
x=50
Number of 5 paise coins =3x=150.
