Question

Adam is 20 years younger than Brian. In two years Brian will be twice as old as Adam.

How old are they now?​

Answer 1

Answer:

Brian is 38 yrs.

Adam is 18 yrs.

Step-by-step explanation:

Let the present age of Brian be 'x' yrs

then the present age of Adam will be 'x - 20' yrs     [∵Adam is 20 yrs

                                                                                     younger than Brian]

After 2 yrs:

Brian will be 'x + 2' yrs

Adam will be '(x - 20) +2' yrs

According to the given question:

x + 2 = 2 (x-20 + 2)

x + 2 =2x - 36

x = 38

Hence,

Brian is 38 yrs and Adam is 18 yrs
