Step-by-step explanation:
there are 2 equations and 2 unknown ..solve for both you will get a = 65 and b = 40
Given : A is 25 year older than B. A age is much above 20 as B is below 85
To Find : Ages of A & B
Solution:
Let say A 's age is x years above than 20
=> A's age = 20 + x
B's age = 85 - x
A is 25 year older than B
=> 20 + x = 85 - x + 25
=> 2x = 90
=> x = 45
A's age = 20 + 45 = 65 Years
B's Age = 85 - 45 = 40 Years
A = 65 Years
B = 40 Years
