A sum of ₹25600 is lent out in two parts in such a way that the interest on one part at 7% for 5 years is equal to that on another part at 9% for 5 years. Find the difference between two parts .
Answer & explanation
Correct answer: option 4
Let the resp principals be P₁, P₂
P₁ x 7% x 5 = P₂ x 9% x 5
P₁ x 35% = P₂ x 45%
P₁ : P₂ = 7 : 9
16R(Total) = 25600
⇒ 1R = 1600
Difference = 2R = 1600 × 2 = 3200/-
