One orange candy costs 30 cents and one strawberry candy costs 40 cents
Buy three and the cheapest one is free

case 1
2 strawberry and 1 orange candy
40c+40c+30c=110c out of which the cheapest one i.e. 30c is waived off so discount amt is 30c

case 2
2 orange and 1 strawberry candy
30+30+40=100c our of which the cheapest one i.e 30c is waived off so discount amount is 30c

Discount1-Discount2=0 hence A

The orange candies are the cheapest candies.
Note that, each of the two customers buys three candies and among them one or more are orange candies. Hence, both the customer will receive same amount of discount.

The correct answer is A.
