Question

Rima has ₹250 in ₹5 and ₹10 coins. If the number of ₹10 coins is twice the number of ₹5 coins, then find the number of ₹5 coins with her.

• A. 20
• B. 25
• C. 15
• D. 10

Answer 1

The correct option is D 10

Let the number of ₹5 coins be $x$
Then, number of ₹10 coins = $2x$

Total money she has
= $(x\times 5)+(2x\times 10)$
$=₹(5x+20x)=25x$.

According to the data provided,
$\Rightarrow 25x=250\Rightarrow x=\frac{250}{25}\Rightarrow x=10$

Therefore, the number of ₹5 coins Rima has is 10.
