Question

Divide rs 3600 into two parts such that if one part be lent at 9%per annum and the other at 10%per annum the total annual income is rs 333

Answer 1

let one part be x, then other part is (3600 - x)

Case 1 : SI = (x * 9 * 1) /100
             => SI = 9x/100

Case 2: SI = [(3600-x)*10*1]/100
              => SI = (3600-x)/10

according to problem, 
9x/100  +  (3600-x)/10 = 333
or, (9x + 36000-10x) = 33300
or, -x + 36000 = 33300
or,  x = 36000-33300
or x = 2700

two parts are 2700 and 900
