Question

A bag contains $10-$paise and $25-$paise coins in the ratio of $17:6$. If the total money in the bag is $Rs.112$, the number of $10-$paise coins is

• A. $35$
• B. $210$
• C. $490$
• D. $595$

Answer 1

The correct option is D $595$

Let the number of $10$ paise coin and $25$ paise coin be $17x$ and $6x$ respectively.

Total money in the bag=$Rs112=11200$ paise

$⟹17x\times 10+6x\times 25=11200$

$170x+150x=11200⟹320x=11200⟹x=35$

Hence the number of $10$ paise coin is $17x=17\times 35=595$
