Divide Rs. 2500 into two parts such that the simple interest on one at 4% for 5 years in double that on the other at 5 % for 3 years.
Let one part is = Rs x
them other part is = Rs (2500 – x)
simple interest (S1) on first part is,
and simple interest (S2) on second part is,
According to question -
Hence one part is Rs 1500 and so other part is Rs 1000
