Reuben​ says, "two days ago i was 20 years old. later next​ year, i will be 23 years​ old." how is this​ possible?
Aneli [31]
Let us always base on the present age. We denote this by x. Now, the age he had 2 years ago would then be denoted as (x-2). Let's equate this to 20 years old.

x - 2 = 20
x = 20 + 2
x = 22 years old
He should be 22 years old now.

Let's check the other condition. After 1 year, his age should be (x+1). Let's equate this to 23 years old.

x + 1 = 23
x = 23 - 1
x = 22


Thus, this is possible if Reuben is 22 years old as of the present.
