Answer 1

Answer:

Let the parts be Rs. ‘x’ and Rs. (10000 – x)

∵ Simple interest = (Principal × Rate × Time)/100

Simple interest on Rs. x at 12.5% after 4 years = (x × 12.5 × 4)/100 = 0.5x

∵ Compound interest after n years = Principal × [(1 + Rate/100)n – 1]

Compound interest on Rs. (10000 – x) at 10% after 2 years

= (10000 – x) × [(1 + 10/100)2 – 1]

= (10000 – x) × 0.21

= 2100 – 0.21x

Now, total interest received = Rs. 3840

⇒ 0.5x + 2100 – 0.21x = 3840

⇒ 0.29x = 1740

⇒ x = 1740/0.29 = Rs. 6000

⇒ 10000 – x = Rs. 4000

∴ Required ratio = 6000 ∶ 4000 = 3 ∶ 2.
