If m, p, and t are positive integers and m < p < t, is the product mpt an even integer?


(1) t – p = p - m
(2) t – m = 16

for mpt to be odd all the variables must be odd.

stmt 1)

says the difference between them is constant.

if t-p = p-m = odd value
then mpt = even.

if the the difference is even , then the product can be either odd or even.

INSUFF

stmt 2)

t-m = 16

to get an even result , either t & m both must be odd or both even.
doesn't give any information of P.

INSUFF.

combining both stmts , still we don't get any additional information .

hence E.
