B) 24
C) 12
D) 4

Solution :
Respective ratio of the number of coins \[=6:3:2\] Respective ratio of their values, \[=6:\frac{3}{2}:\frac{2}{10}\] \[=60:15:2\] Sum of the terms of ratio = 60 + 15 + 2 = 77 \[\therefore \]Value of 50-paise coins = Rs. \[=\left( \frac{15}{77}\times 30.8 \right)=Rs.\,6\] \[\therefore \]Their number \[=6\times 2=12\]You need to login to perform this action.
