Question

A bag contains Rs $90$ in coins. If coins of $50$ paise, $25$ paise and $10$ paise are in the ratio $2:3:5$, then the number of $25$ paise coins in the bag are

• A. $120$
• B. $130$
• C. $135$
• D. $140$

Answer 1

Answer: (A)

$120$

Let there be 2x, 3x and 5x coins of 50 p, 25 p, and 10 p.
$\Rightarrow 50\times 2x+25\times 3x+10\times 5x=90\times 100$
$\Rightarrow 225x=9000$
$\Rightarrow 3x=\frac{9000}{225}\times 3=120$.
