If a, b, c, d are non zero integers, is a/b + c/d greater than 2?
(1) a > b
(2) d > c
From statement 1 , a > b
So , a/b >1
No information about c and d . So not sufficient.
From statement 2 , d > c
So , c / d <1
No information about a and b . So not sufficient.
Together ,
We know a / b > 1 . We dont know how much greater.
If it's just greater , say a/b = 1.5 and c/d is very lesser than 1 , say c/d = -2
Then a/b + c/d is NOT greater than 2.
Else , if a/b is much bigger than 1 say a/b = 5
and c/d is just lesser than 1 say c/d = -.5
Then a/b +c /d = 5-.5 = 4.5 and is greater than 2.
Yes or No ...both are possible...
Option E is the answer.
Please give me KUDOs if you liked my explanation.
