What will be the compound interest earned on a sum in two years?

I. The simple interest on the same amount at the same rate of interest in two years is Rs. 800.

II. The amount becomes more than double at compound interest in 10 years.

III. The simple interest on the same amount at the same rate of interest in three years is Rs. 1,200.

From (I) & (III), SI for 1 year = Rs. 400 ∴ 400 = P × R × 1/100 From this we cannot get the answer and also statement II is not sufficient to answer the question.
