The simple interest received after 2 years on Rs (x + 800) at the rate of 20% p.a is Rs (2x – 1800). The amount received on Rs 4x when invested at 50% p.a compound interest, compounded annually for 2 years can be:

B Rs. 11925 Correct Answer Incorrect Answer
C Rs. 15161 Correct Answer Incorrect Answer
D Rs. 15572.50 Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

According to the question,
{(x + 800) × 2 × 20}/100 = (2x – 1800)
=> 2x + 1600 = 10x – 9000
=> 8x = 10600
=> x = 1325
Therefore, required amount received = 4x . (1 + 50/100)2 = Rs. 11925
