Question

find the compound interest @ 10% per annum for 2 years a principal in 2 years @ 10% per annum is 200 is simple interest

Answer 1

Answer:

Rs. 210

Step-by-step explanation:

Given: SI = 200

R = 10%

T = 2 years

SI = PRT/100

⇒ 200 = P * 10 * 2 ÷ 100

⇒ 200 = P ÷ 5

⇒ P = 1000

CI₁ (for the first year) = P * R ÷ 100

⇒ CI₁ = 1000 * 10 ÷ 100

        = 100

⇒ A₁ = P + CI₁

    = 1000 + 100

    = 1100

⇒ CI₂ = 1100 * 10 ÷ 100

     = 110

⇒ Total CI = CI₁ + CI₂

                 = 100 + 110

                 = 210
