Options:

Rs.250000

Rs.200000

Rs.350000

Rs.550000

Correct Answer:

Rs.250000

Explanation:

The Formula that we used here is -

Amount = P$(1 \;+\; \frac{R}{100})^t$

280900 = P ( 1 + \(\frac{6}{100}\) )²

280900 = P ( \(\frac{53}{50}\) )²

280900 × \(\frac{50}{53}\) × \(\frac{50}{53}\) = P

P = 2,50,000
