D. Tk. (1.5x+175)
E. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

The cost of the first 1.5 kg of molasses is given as Tk. x.

So, the cost of the remaining 5 - 1.5 = 3.5 kg of molasses will be 3.5 × 50 = Tk. 175.

Therefore, the total cost of 5 kg of molasses will be:

Cost of first 1.5 kg + Cost of remaining 3.5 kg
