Question
Rs. 7500 is invested in scheme βAβ for 3 years and
Rs. 6000 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 = (7500 Γ 16 Γ 3) Γ· 100 = Rs. 3600 Let the rate of simple interest offered by scheme βBβ = βk%β p.a. ATQ; (6000 Γ 2 Γ k) Γ· 100 = 3600 Or, 120k = 3600 Or, k = (3600/120) = 30 So, rate of simple interest offered by scheme βBβ = 30% per annum.
