Question
Jaideep invested two equal sums at 12% simple
interest p.a. for 8 years and 10 years respectively. If the difference in interest earned is Rs.14,688. Find the sum invested by Jaideep?Solution
Let Principal = Rs.x , T1= 8 yrs, T2= 10yrs and Rate =12%p.a `(x xx 10xx 12)/100-(x xx 8xx 12)/100=14688 =>(120x)/100-(96x)/100=14688 ` ⇒`(24x)/100` = 14,688 ∴ `x = Rs. 61200`
