Question

two numbers are in ratio 5 is to 7 the sum of the number is 156 find the number

Answer 1

Answer:

Step-by-step explanation:

Let one number be "X"

Let the other number be "Y"

Given: X/Y =5/7 so 7X=5Y Or X=5Y/7 (1)

      Also X+Y=156

        Substituting value of X from equation (1)

      5Y/7+Y=156  Or  5Y+7Y/7=156

                                  12Y/7=156

                                 12Y=156*7

                                 12Y=1092

                                   Y=91

Substituting value of Y in equation (1)

    X=5Y/7

    X=5*91/7

    X=455/7

  X=65
