A bag contains Rs. 550 in the form of 50 p, 25 p, and 20 p coins in the ratio 2 : 3 : 5. The difference between the amounts that are contributed by the 50 p and the 20 p coins is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 0.
Calculation:
Number of 50 p coins = 2x
Number of 25 p coins = 3x
Number of 20 p coins = 5x
Total amount (in paisa) = 550 × 100 = 55000
According to the question;
⇒ (50 × 2x) + (25 × 3x) + (20 × 5x) = 55000
⇒ 100x + 75x + 100x = 55000
⇒ 275x = 55000
⇒ x = 200
Amount of 50 p (in Rs.) = 100x = 200
Amount of 20 p (in Rs.) = 100x = 200
Required difference = 200 - 200 = 0
