Divide 4500 into two parts such that 5% of the first part is equal to 10% of the second part.
Let the first part be x. So the second part will be 4500-x
According to the question,
x*5/100 = (4500-x)*10/100
x/20= (4500-x)/10
x/20=9000-2x/20
x=9000-2x, x=3000
so, the first part is 3000, second is 1500
