According to the title, we have:
99<a<110 and a is a prime number
So a=103
b is the greatest 1digit number so b = 9
a+b=103+9=112

The title is missing some information: Each person has a pancake.
So there are: \(4.3.9=108\left(people\right)\) in the party.

2 x 2 + 1 = 5
3 x 2 + 1 = 7
5 x 2 + 1 = 11
7 x 2 + 1 = 15
11 x 2 + 1 = 23
13 x 2 + 1 = 27
So,there are 4 jillyprimes which are less than 15 : 2 ; 3 ; 5 ; 11
