    A box contains one-rupee, fifty paise and twenty five paise coins. The total number of coins is 378. The ratio of values of the above coins is 13:11:7. Find the number of fifty paise coins?

    A) 78                                

    B) 164

    C) 168                              

    D) 132

    Correct Answer: D

    Solution :

    The ratio of values of the coins is 13:11:7. Then, ratio of the number of the coins is \[13\times 1:11\times 2:7\times 4\]= 13 : 22 : 28 Now, \[13x+22x+28x\]= 378 \[63x=378\]  \[x=6\] Hence, the number of fifty paise coins \[=22\times 6\] \[=132\]
