Question

A number is divided into two parts such that one part is 10 more than the other.if two parts are in the ratio 5:3 find the number and the two parts.

Answer 1

let the one number be X
second number be x+10
x/x+10=3/5
5x=3x+30
5x-3x=30
2x=30
x=15 (one number)
second number=25

Answer 2

difference in the ratio is (5-3) 2 = difference in the part is 10

10/2 * 1 = 5
1 ratio = 5
therefore 5 ratio = 25
one part is 25 . other part is 15.
