Question

Gill borrowed a sum of money from Jack at the rate of 8% per annum simple interest for 4 years, 10% per annum for next 6 years and 12% per annum for the period beyond 10 years. The total interest paid by Gill is ₹12160 at the end of 15 years. The sum borrowed by him is what ?​

Answer 1

Answer:

8000

Step-by-step explanation:

12160 = (4×8/100) + (10×6/100) + (12×5/100)

12160 = (32x/100) + (60x/100) + (60x/100)

12160 = 152x/100

(12160×100)/152 = x

x = 8000
