59 and 53 are the two largest primes less than 60. 59+53 = 112
There are 168 prime numbers less than 1,000.
The twin primes that are greater than 20 but less than 30 are (23, 25) and (29, 31). However, since 25 is not prime, the only valid twin primes in that range are (29, 31). Twin primes are pairs of prime numbers that have a difference of two.
The median of the 12 primes less than 40 is 15.
