1)If X>Y
2)If X<Y
3)If X≥ Y
4)If X≤ Y
5)If X=Y or cannot be established

Answer 5)If X=Y or cannot be established
(X – 12)(X+7) = 0
X = 12, -7
(Y -13)(Y+4) = 0
Y = -4,13
13,12,-4,-7
2)I. 4X2 + 17X + 15 = 0
II. 12Y2 + 19Y + 5 = 0

Answer 4)If X≤ Y
(X+3)(4X+5) = 0
X = -3, -5/4
(4X+5)(3X+1) = 0
X = -1/3,-5/4
-0.33,5/4,-5/4,-1/3
3)I. X2 – 35X + 306 = 0
II. Y2 – 14Y – 51 = 0

Answer3)If X≥ Y
(X – 17)(X-18) = 0
X = 17,18
(Y-17)(Y+3)= 0
Y = 17,-3
18,17,17,-3
4) I. 2X2 – 9X + 9 = 0
II. Y2 – 11Y + 24 = 0

Answer4)If X≤ Y
(2X-3)(X-3) = 0
X= 3,3/2
(Y-8)(Y-3) = 0
Y = 8,3
8,3,3,3/2
5) I. X2 – 7X + 12 = 0
II. Y2 – 8Y+16 = 0

Answer B) 653.1
1198.2 – 108.4 = 436.7 + ?
1089.8 = 436.7+653.1
7)20 % 650 + 150 % ? = 2005
A)1254
B)1253

Answer D) 1250
130 + (150x/100) = 2005
2005 – 130 = 150x/100
3x/2 = 1875
X = (1875×2)/3 = 1250
