Question

a 21. The ratio of two numbers is 7 : 5. If their difference be 30 then find the numbers.​

Answer 1

Answer:

105 and 75

Step-by-step explanation:

Let the number be x.

By question,

    7x -5x = 30

or 2x =30

or   x =30/2

      x = 15

Now, replacing the value of x,

7x = 7*15 = 105

5x = 5*15 = 75
