$120$ coins of $25$ paisa and $50$ paisa together total Tk. $35$ . Number of $25$ -paisa coins is—

a $80$
b $90$
c $100$
d $110$

ব্যাখ্যা

Converting to paisa, $25x+50(120-x)=3500$ where $x$ is the number of $25$ -paisa coins; this gives $25x=2500$ , so $x=100$ . Therefore there are $100$ coins of $25$ paisa.
