II) y2 – 4y – 77 = 0
3)
I) x3 + (156 ÷ 4) – 12 % of 50 = 60
II) y2 – 12y + 27 = 0
4)
I) 2x2 – 5x – 33 = 0

d) 112 %
e) 130 %
Answers :
1) Answer: a)
8x – 3y = -4 –> (1)
9x – 4y = -2 –> (2)
By solving the equation (1) and (2), we get,
X = -2, y = -4
X > y
2) Answer: e)
I) x2 + 5x – 126 = 0
(x – 9) (x + 14) = 0
X = 9, -14
II) y2 – 4y – 77 = 0
(y – 11) (y + 7) = 0
Y = 11, -7
Can’t be determined
3) Answer: d)
I) x3 + (156 ÷ 4) – 12 % of 50 = 60
X3 + (156/4) – (12/100)*50 = 60
X3 = 60 – 39 + 6
X3 = 27
X = 3
II) y2 – 12y + 27 = 0
(y – 9) (y – 3) = 0
Y = 9, 3
X ≤ y
4) Answer: c)
I) 2x2 – 5x – 33 = 0
2x2 + 6x – 11x – 33 = 0
2x (x + 3) – 11 (x + 3) = 0
(2x – 11) (x + 3) = 0
X = 11/2, -3 = 5.5, -3
II) y2 – 17y + 66 = 0
(y – 11) (y – 6) = 0
Y = 11, 6
X < y
5) Answer: c)
I) x2 = ∛140608 + (3/35)*140
X2 = 52 + 12 = 64
X = 8, -8
II) y3 = 729
Y = 9
X < y
6) Answer: d)
The marked price of item A
= > 300*(125/100) = Rs. 375
The cost price of item C = Rs. 400
Required ratio = 375 : 400 = 15 : 16
7) Answer: a)
The average cost price of item B, D and F together
= > (500 + 600 + 250)/3
= > 1350/3 = Rs. 450
8) Answer: c)
The selling price of item C = 400*(120/100) = Rs. 480
The selling price of item E = 650*(90/100) = Rs. 585
Required difference = 585 – 480 = Rs. 105
9) Answer: b)
The cost price of item P
= > 75 % of cost price of item D
= > (75/100)*600 = Rs. 450
The selling price of item P = The cost price of item B = Rs. 500
Profit % = [(500 – 450)/450]*100 = 11.11 % = 11 % profit
10) Answer: d)
The cost price of item A and E together
= > 300 + 650 = Rs. 950
The cost price of item D and F together
= > 600 + 250 = Rs. 850
Required % = (950/850)*100 = 111.76 % = 112 %
