A. 5,000

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

Net income from gross income of 20,000 tk = 80% of 20,000 = (0.8)(20,000)

Net income from gross income of 30,000 tk = 80% of 30,000 = (0.8)(30,000)

So, the INCREASE in net income = (0.8)(30,000) - (0.8)(20,000)

= (0.8)(30,000 - 20,000)

= (0.8)(10,000)

= 8,000 tk. Ans

A. Tk. (x+150)
B. Tk. (1.5x+150)
C. Tk. (x+175)
D. Tk. (1.5x+175)
E. None of these

View Answer	Favorite Question	Report

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).
