A. 2

There is only one even prime number and the sum of three odds will never be even, so two numbers must be odd and one number must be even.

a + b + c = 100

As said above one of the prime number needs to be 2.

2 + b + c = 100

b + c = 98 ... (1)

We know the difference between b and c is 36.

c - b = 36 ... (2)


(1) - (2) ... 2b = 62 => b = 31

c = 36 + 31 = 67 - Answer: 5

E

numbers are 2, 31 and 67

can get that by solving the below two equations:
a+b = 98
a-b = 36
