Question

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

Answer 1

  let one part of number = x
           therefore ,  other part of number = x+10
   according to question ,
             x+10/x=5/3
           3(x+10)= 5x
           3x+30 =5x
             30 = 5x -3x
             30 = 2x
     or x=30/2
         x=15

therefore one part of number = 15
and other part = 15+10 =25

hence number = 15+25 =40
