Question
Ajay invested Rs.a in SI at 9% rate of interest per
annum for 10 years. Vishal invested the same amount in SI at 5% rate of interest per annum for 6 years and the difference between the interest obtained by Ajay and Vishal is Rs.1800. Find the amount invested by Vishal.Solution
According to question, => (a × 9 × 10)/100 – (a × 5 × 6)/100 = 1800 => 90a/100 – 30a/100 = 1800 => 60a/100 = 1800 => a = Rs.3000
