13, a, b, c are four distinct numbers and HCF of each pair of numbers (13, a) (13, b) (13, c) is 13

13, a, b, c are four distinct numbers and HCF of each pair of numbers (13, a) (13, b) (13, c) is 13, where a, b, c are less than 60 and a less than b less than c. What is the value of a+c/b?

A and B are two prime numbers such that A greater than B and their LCM is 209. The value of B^2-A is: (a) 111 (b) 102 (c) 121 (d) 109
