Discussion

Explanation:

Suppose the can initially contains 15x and 9x of mixtures A and B respectively.

Quantity of A in mixture left = 5x-58×8 = 5x - 5 liters

Quantity of B in mixture left = 3x-38×8 = 3x - 3 liters

5x-53x-3+8=57

⇒ 35x – 35 = 15x + 25

⇒ x = 3

So, the can contained 15 litres of A.

Hence, option (c).
