There are two ancient banyan trees. 500 years ago, some scholars said that the age of these two banyan trees was 4000 years old, and the age difference was 1000 years old. How old are these two banyan trees now?
Suppose one banyan tree is now X years old and the other is Y years old.
x-y= 1000……( 1)
(x-500)+(y-500)= 4000 x+y = 5000……(2)
( 1)+(2)
2x=6000
x=3000
y=2000
One banyan tree is now 3000 years old and the other is 2000 years old.
