• A. $100$
• B. $140$
• C. $120$
• D. $80$

Answer 1

Answer: (C)

$120$

Let no. of Coin $1$ rupee, $50$ paise and $25$ paise be $2x.3x$ and $10x$ respectively
ATQ
$2x+\frac{3x}{2}+\frac{10x}{4}=72$
$\frac{8x+6x+10x}{4}=72$
$24x=72\times 4$
$x=12$
$\therefore$ No. of $25$ paise Coin $=10\times 12=120$.
