1. Molasses cost Tk. x for the first 1.5 kg at 'Prabartana'. All amount in addition to first 1.5 kg cost Tk. 50 per kg. How much does it cost to buy 5 kg molasses from 'prabartana'?
- A. Tk. (x+150)
- B. Tk. (x+150)
- C. Tk. (x+150)
- D. Tk. (x+150)
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
= Tk. x + Tk. 175
= Tk. (x + 175)
Hence, the cost of 5 kg of molasses from 'Prabartana' is Tk. (x + 175).
