  • A 25 years ✔ ✖
  • B 20 years ✔ ✖
  • C 45 years ✔ ✖
  • D 30 years ✔ ✖
Correct Answer: Option C

Explanation

 
Let x be John's age.
Since Mary is 25 years older than John, her age is x + 25.
 The sum of their ages is 65, so x + (x + 25) = 65.
 Simplifying this equation gives 2x = 40, so x = 20.
 Therefore,
 John is 20 years old and Mary is 20 + 25 = 45 years old.
