Question

If a and b are twin primes and a?-b2 = 120, then their average is​

Answer 1

The twin prime numbers are pair of prime numbers whose difference is equal to 2

Now, for 120, first divide 120 by 2 , we get 60 and then by adding 1 and subtracting 1 , we get two numbers 

60-1=59

60+1=61

Here, 59 and 61 are prime numbers which have a difference of 2 and add up to form 120

59+61=120
