1. One-third of Ratan's investment in National Savings Certificate is equal to one-half of his investment in FDR. If he has Tk. 1,50,000 as total investment, how much he invested in savings certificate?
- A. Tk. 30,000
- B. Tk. 30,000
- C. Tk. 30,000
- D. Tk. 30,000
Answer: Option D
Explanation:
According to the problem, one-third of Ratan's investment in NSC is equal to one-half of his investment in FDR. We can write this as:
(1/3)x = (1/2)(150,000 - x)
Simplifying this equation, we get:
2x = 3(150,000 - x)
2x = 450,000 - 3x
5x = 450,000
x = 90,000
Therefore, Ratan invested Tk. 90,000 in National Savings Certificate.
