Answer 2

Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Number of coins with denomination Rs. 1, 50 paise and 25 paise.

Ratio would be 12:10:7

So, Number of coin Rs. 1 be 12x

Number of coin 50 paise be 10x

Number of coin 25 paise be 7x.

Total worth = Rs. 75

According to question,

$12x+10x\times 0.50+7x\times 0.25=75\\\\12x+5x+1.75x=75\\\\18.75x=75\\\\x=\dfrac{75}{18.75}\\\\x=4$

Hence, number of 25 paise coins be $7x=7\times 4=28$

Therefore, Option 'a' is correct.
