Answer:hey brainlymate here is your answer
Rate = 10 % per annum Compound Interest (CI) = Rs 210 Time (t) = 2 years By using the formula, Let P be ‘x’ CI = A – P 210 = P (1 + R/100) n – P = P [(1 + R/100)n – 1] = x [(1 + 10/100)2 – 1] = x [(110/100)2 – 1] 210 = x ((1.1)2 – 1) x = 210 / ((1.1)2 – 1) = 210/0.21 = Rs 1000 ∴ The required sum is Rs 1000.
