Answer 1

The correct option is A 50
The ratio of ₹ 5, ₹ 10 and ₹ 2 rupee coins are $2:3:5.$
Let there are $2x$, $3x$ and $5x$ number of ₹ 5, ₹ 10 and ₹ 2 coins respectively.

Therefore, total number of money in the bag is,
$2x\times 5+3x\times 10+5x\times 2$, which is equal to 500.

Hence,
$2x\times 5+3x\times 10+5x\times 2=50010x+30x+10x=50050x=500x=\frac{500}{50}x=10$

So, the number of two rupee coin is, $5\times 10=50.$
