Question
Rs. 9500 is invested in scheme βAβ for 3 years and
Rs. 8000 is invested in scheme βBβ for 2 years. Scheme βAβ offers simple interest of 16% p.a. If the interest received from both the schemes are equal, then find the rate of simple interest (p.a.) offered by scheme βBβ.Solution
Interest received from scheme βAβ = 9500 Γ 16 Γ 3 Γ· 100 = Rs. 4560 Let the rate of simple interest offered by scheme βBβ = βk%β p.a. ATQ; 8000 Γ 2 Γ k Γ· 100 = 4560 Or, 160k = 4560 Or, k = (4560/160) = 28.5 So, rate of simple interest offered by scheme βBβ = 28.5% per annum.
