one part is 15 more than the other. if the two
parts are in the ratio 7:4 find the number​

Answer 1

Answer:

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
