A sum of Rs 315 consists of 25 paise, 50 paise and 1 Re coins in the ratio 3 : 4 :6. What is the number of each kind of coin respectively?.

216, 144, 27

108, 144, 216

27, 72, 216

120, 35, 108

Explanation:

25 paise = 25/100 Rs, 50 paise = 50/100 Rs
So value ratio of these coins become = 3*(25/100) : 4*(50/100) : 6*(1)
= 3/4 : 2 : 6 = 3 : 8 : 24
So 25 paise coins value= [3/(3+8+24)] * 315 = Rs 27, so coins = 27 * (100/25) = 108
Similarly find others.
