Question

a number is twice another number.when the larger is subtracted from 50,the result is 2 more than when smaller is subtracted from 40.find the number

Answer 1

Given =A number is twice another number.

Let the smaller number be x and
Let the larger number be 2x.

Now , A.T.Q.

 50 - 2x = 40 - x + 2
-2x + x = 42 - 50
- x =  -8
x = 8

Hence the smaller number is 8

Now for bigger number 2x= 2(8)  = 16

Answer 2

Given =A number is twice another number.

let ,
       smaller number be x 
and  the larger number be 2x.
so ,
 
A.T.Q. ===>    50 - 2x = 40 - x + 2
===>    2x + x = 42 - 50
===>     - x =  -8
===>    x = 8

Hence the smaller number        = x =  8
 and bigger number =         2x =  2(8)  =   16
