Answer» Given, Time period, T = 15 years Rate of interest for JATIN, R1 = 13% Rate of interest for Gabru, R2 = 15% Let the original amount of loan TAKEN by Jatin from the bank be Rs. x. We KNOW the FORMULA for simple interest- SI = (P × T × R)/100 Where, P = Principal amount T = Time period R = Rate of interest Profit = Rs. 1470 ⇒ (P × T × R2)/100 – (P × T × R1)/100 = 1470 ⇒ (x × 15 × 15/100) – (x × 13 × 15/100) = 1470 ⇒ x = Rs. 4900 ∴ The original amount of loan taken by Jatin from the bank = Rs. 4900 |
