Question

A lady has only $25$ paise and $50$ paise coins in her purse. She has a total of $120$ coins and total amount is Rs. $50$. The number of coins of each type in her purse, respectively, is

• A. $90,30$
• B. $60,60$
• C. $40,80$
• D. $70,50$

Answer 1

The correct option is C $40,80$

Let the number of $25$ paise coins be $n$.

Then the number of $50$ paise coins will be $120-n$
$\therefore 25n+50\times (120-n)=50\times 100$
$\therefore n=40$
Hence, number of $50$ paise coins $=120-40=80$
Number of $25$ p coin $=40$

Number of $50$ p coin $=80$
