    B)  120    

    C)  100

    D)  135

    Correct Answer: B

    Ratio of values of 50 paise, 25 paise and 10 paise coins \[=\frac{2}{2}:\frac{3}{4}:\frac{5}{10}=1:\frac{3}{4}:\frac{1}{2}=4:3:2\] Sum of the ratios \[=4+3+2=9\] \[\therefore \]Value of 25 paise coins\[=\frac{3}{9}\times 90\]= Rs. 30 \[\therefore \]Number of 25 paise coins \[=30\times 4=120\]
