Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 80
The ratio of the number of coins of 25 paise, 50 paise, Rs.2, and Rs.5 is 5 ∶ 4 ∶ 3 ∶ 1, respectively.
If the total amount of the coins is Rs.285
According to the question
5 × 0.25 + 4 × 0.5 + 3 × 2 + 1 × 5 = 285
1.25 + 2 + 6 +5 = 285
14.25 units = 285
1 unit = 285/14.25 = 20
Hence, the difference between the number of 25 paise and Rs.5 coins (4 units ) = 4 × 20 = 80
