Is the positive integer p the sum of the positive prime numbers
m and n?
(1) m - n = 8
(2) p = 50
m and n?
(1) m - n = 8

m,n are prime numbers.
m=3,n=5
p=8.. not 50>>NO
m=43,n=7
p=50.>>YES
combining:
m-n=8 and p=50
m-n=8 and m+n = 50
m=29, n=21
n is not prime.
Hence no such m,n are possible.

pick C
Hope this helps!!
