Correct Answer: 150, 180, and 150


Solution : Given:
The ratio of values = 5 : 3 : 1
Ratio of their numbers = 10 : 12 : 10 = 5 : 6 : 5
⇒ Number of 50 paise coins $=\frac{5}{16}×480 = 150$
⇒ Number of 25 paise coins $=\frac{6}{16}×480 = 180$
⇒ Number of 10 paise coins $=\frac{5}{16}×480 = 150$
Hence, the correct answer is 150, 180, and 150.
