Answer» Correct Answer - Option 3 : 53

Given:

Sum of the three prime numbers = 84

Concept used:

Prime number = It is the number that has only two factors, one and itself

If the sum of three prime numbers is even then one prime number must be 2

Calculation:

Let the one prime number be x, then another prime number is x + 24

Sum of the three prime number = 84

⇒ 2 + x + x + 24 = 84

⇒ 2x = 58

⇒ x = 29

Another prime number = x + 24 = 29 + 24 = 53

∴ The greatest prime number is 53
