1) w+ c > 50

For this to be true, Let's say C = 100 and W=-10
c+w = 90 >50 , Ans. NO

if C= 30 w = 21 c+w >50 ...w>0 Yes


Insuff

2) c>48
dont know abything about w

Togeher,

If c =49, C is an integer

w+49>50. Thus, w>1


Suff

AnS C

if we take both the statements together then
lets consider c = 100 w = -10
w+c = 90 i.e. w+c > 50 , thus, here W < 0..
its not sufficient..
please lemme know if i am missing something..

But, what if c=65 & w=-10, then w+c = 55, which is greater than 50. But, w is <0.

IMO E. What is the source of this question?

u are missing some good books, perhaps :lol: if your source quotes a wrong OA for a simple question like this, you have fair enough reason to get rid of that source! :twisted:
