Question

In a piggy bank, the number of $25$ paise coins are five times the number of $50$ paise coins. If there are $120$ coins find the amount in the bank ?

• A. Rs. $25$
• B. Rs. $10$
• C. Rs. $35$
• D. Rs. $40$

Answer 1

Answer: (C)

Rs. $35$

Let number of $50$ paise coins $=x$
then number of $25$ paise coins $=5x$
Given total number of coins $=120$
$\Rightarrow x+5x=120$
$\Rightarrow 6x=120$
$\Rightarrow x=\frac{120}{6}=20$
$\therefore$ Number of $50$ paise coins $=20$
Thus Amount $20\times 50=$ Rs. $10$
And number of $25$ paise coins $=5\times 20=100$
Thus amount $=25\times 100=$ Rs. $25$
Hence, total amount $25+10=$ Rs. $35$.
