Question

4. A number is twice of another. If the larger number is subtracted from 30, the result is 2 less than the smaller number subtracted from 22. Find the numbers.​

Answer 1

Answer:

let first no be x

so, another no=2x

A/Q

30-2x=22-x+2

30-24=-x+2x

x=6

therefore, first no=6 another no=2x=2*6=12

Answer 2

Answer:

20 and 10

Step-by-step explanation:

let the 2 numbers be x and y.

Case1:    x>y

              x=2y         -------(1)

      30 - x=22 - y - 2

       x - y =10         --------(2)

    put (1) in  (2)

     2y - y = 10

            y = 10

    x= 2y= 2*10=20

Case2:   y>x

             y=2x    -------(1)

     30 - y=22 -  x - 2

       y - x =10         --------(2)

put (1) in  (2)

     2x - x = 10

            x = 10

    y= 2x= 2*10=20

therefore the 2 no. are 20 and 10

hope this is helpful:)
