A total of 324 coins of 20 paise and 25 paise make a sum of Rs. 71. The number of 25-paise coins is

Answer & Solution
Correct Answer: Option B
Let the number of 20-paise coins be x. Then, number of 25-paise coins = (324 - x).
Therefore 0.20 x x + 0.25 (324 - x) = 71 ⇔ 20x + 25 (324 - x) = 7100
⇔ 5x= 1000 ⇔ x = 200. Hence, number of 25-paise coins = (324 - x) - 124.
