Question

Raju invests two equal amounts earning 10% and 18% of interest annually. If the interest on them earned is 1260 in a year, then the sum invested in each is

Answer 1

let money invested on each be x

10% of x + 18% of x = 1260

x/10 + 9x/50 = 1260

14x/50 = 1260

x = 4500

so total amount invested = 9000
