Ajay invested Rs.a in SI at 5% rate of interest per annum for 8 years. Vishal invested the same amount in SI at 3% rate of interest per annum for 4 years and the difference between the interest obtained by Ajay and Vishal is Rs.1400. Find the amount invested by Vishal.
According to question, => (a × 5 × 8)/100 – (a × 3 × 4)/100 = 1400 => 40a/100 – 12a/100 = 1400 => 28a/100 = 1400 => a = Rs.5000
