Solution : Given: A bag contains INR 550 in the form of 50 p, 25 p, and 20 p coins in the ratio 2 : 3 : 5. So, the ratio of the amount contributed = 100 : 75 : 100= 4 : 3 : 4 So, the value 20 p coins in the bag is = $\frac{4}{11}×550=200$ And the value 50 p coins in the bag is = $\frac{4}{11}×550=200$ The difference between the amounts that are contributed by the 50 p and the 20 p coins is (200 – 200) = 0. Hence, the correct answer is INR 0.
