B. 64

C. 32

D. 16

Answer: Option B

Solution(By Examveda Team)

Total Amount = Rs. 56
Number of coins Ratio of 50 paise coin and 25 paise coins = 2 : 1
Number of coins Ratio of Rs. 1 coin and 50 paise coins = 1 : 4
∴ Number of coins Ratio of Rs. 1 : 50 paise : 25 paise = 1 : 4 : 2

Ratio of coin's value
Rs. 1 : 50 paise : 25 paise (value) = 1 : 2 : 0.50
(Multiply by 2 to remove the fraction value in above ratio)
i.e Rs. 1 : 50 paise : 25 paise (value) = 2 : 4 : 1
Value of 50 paise coin in Rs. 56 = $$\frac{4}{{7}} \times 56 = 32 $$
Number of 50 paise coin is = 32 × 2 = 64
