1) x*y = 25
2) x and y are integers such that x>y
E)
As X = -1, y = -25: X+Y = -26
or
X = 25 , Y = 1: X + Y = 26
1) x*y = 25
2) x and y are integers such that x>y
E)
As X = -1, y = -25: X+Y = -26
or
X = 25 , Y = 1: X + Y = 26

target find value of x+y
#1
x*y = 25
possible pairs of x,y ; (-1,-25);(1,25);(125,1/5) ;
insufficient
#2
x and y are integers such that x>y
can be any value of x& y ; insufficient
from 1 &2
possible values of x,y ; ( -1,-25) ; ( 25,1)
we get x+y as ; -26 and 26
insufficient
OPTION E
