Question

jackson's age was 2/5 of the age he will be 20 years from now 7 years ago. How old is jackson now?

Answer 1

Let the age of Jackson be x .
Then, A.T.Q
 
   x - 7 =  2/5 ( x + 20 )
5(x - 7)= 2( x + 20 )
5x -35 = 2x + 40
5x - 2x = 40 + 35
3x = 75
x= 25

Hence the age of Jackson is 25 years.

Answer 2

Solution :
         Let the Present age Of Jackson (in Years) = x
         Therefore , Jackson's age 7 years ago = x - 7
                   and Jackson's age after 20 years = x+20
       According to question ,
            x - 7 = 2/5 (x+20)
            5(x - 7 )= 2(x+20)
             5x - 35 = 2x +40
             5x - 2x = 40+35
             3x =75
               x= 75/3
               x= 25

Hence , Present age of Jackson is 25 Years !!
