Question

A number is divided into 2 parts such that 1part is 15 more than the other if the parts are in ratio 7:4find the numbers​

Answer 1

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 5:3, find the number

and the two parts.

solution:

       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

hope this helps you!!!
