Question
Deepa placed Rs. 3500 at R% p.a. simple interest for 6
years and Rs. 1500 at (R + 4)% p.a. simple interest for 6 years. If her total interest is Rs. 4560, find the amount she will get if Rs. 2500 is invested at (R + 3)% p.a. simple interest for 2 years.Solution
According to question; 3500 × R/100 × 6 + 1500 × (R + 4)/100 × 6 = 4560 Or, 210R + 90R + 360 = 4560 Or, 300R = 4200 Or, R = 14 Desired amount = 2500 + 2500 × 0.17 × 2 = 2500 + 850 = Rs. 3350
