Adarsh invested ₹12,600 in three parts in such a way that SI on 1st part at 2% per annum for 3 years is equal to SI on 2nd part at 3% per annum for 4 years is equal to SI on 3rd part at 4% per annum for 5 years. Find the SI on each part.
Answer & explanation
Correct answer: option 1
P₁ x 2% x 3 = P₂ x 3% x 4 = P₃ x 4% x 5
P₁ x 6 = P₂ x 12 = P₃ x 20
P₁ : P₂ : P₃ = 10 : 5 : 3
18R(Total) = 12600
⇒ R = 700
S.I. on each part = 420
