Harsh invested ₹62500 in three parts in such a way that SI on 1st part at 4% per annum for 5 years is equal to SI on 2nd part at 3% per annum for 2 years is equal to SI on 3rd part at 5% per annum for 1 years. Find the SI on each part.
Answer & explanation
Correct answer: option 3
Let three parts are P1, P2 and P3
ATQ
P₁ x 4% x 5 = P₂ x 3% x 2 = P₃ x 5% x 1
P₁ x 20 = P₂ x 6 = P₃ x 5
P₁ : P₂ : P₃ = 6 : 20 : 24 = 3 : 10 : 12
25R(Total) = 62500
⇒ 1R = 2500
⇒ P₁ = 2500 × 3 = 7500
S.I. on each part = P₁ x 20% = 7500 x 20% = 1500
