Answer 2

Solution :-

Let the sum is Rs. x .

So,

→ P = Rs. x

→ R = 20%

→ T = 1 year

then,

→ SI = (P * R * T)/100 = (x * 20 * 1)/100 = 0.2x .

→ A = P + SI = x + 0.2x = 1.2x

Now,

→ P (for second year) = 1.2x

→ T = 1 year

→ R = 20% .

So,

→ SI = (1.2x * 20 * 1)/100 = 0.24x

A/q,

→ 0.24x = 9990

→ x = Rs.41625 (Ans.)
