Question

A bag contains $50$ paise, $1$ rupee and $2$ rupee coins in the ratio $2:3:4$. If the total amount is $Rs.240$, what is the total number of coins?

• A. $90$
• B. $150$
• C. $180$
• D. $200$

Answer 1

The correct option is C $180$

Total value in one set $=Rs.(2\times \frac{1}{2}+3\times 1+4\times 2)$
$=Rs.12$
Number of sets $=240÷12=20$
In each set, there are $9$ coins so total number of coins $=20\times 9=180$.
