    Rakesh had some amla candies. He gave two third of the total candies to Rajan. One fifth to Sumitra and the remaining candies were given to Prasad. If Rakesh had 90 candies, then how many candies were given to Prasad?

    A)  9                                

    B)  13           

    C)  14                               

    D)  12

    Correct Answer: D

    Solution :

    (d)\[90\times \left( 1-\frac{2}{3}-\frac{1}{5} \right)=90\times \left( \frac{15-10-3}{15} \right)\] \[=\bcancel{90}\times \frac{2}{\bcancel{15}}=12\]
