3x2 + 6x + 7x + 14 = 0

3x(x + 2) + 7(x + 2) = 0

(3x + 7) (x + 2) = 0

X = -7/3, -2 = -2.33, -2

II) 9y2 + 29y + 22 = 0

9y2+ 18y + 11y + 22 = 0

9y(y + 2) + 11(y + 2) = 0

(9y + 11) (y + 2) = 0

Y = -11/9, -2 = -1.22, -2

I) 4x2 โ x – 18 = 0

4x2 + 8x โ 9x – 18 = 0

4x (x + 2) -9 (x + 2) = 0

(4x โ 9) (x + 2) = 0

X = 9/4, -2 = 2.25, -2

II) 5y2 + 11y – 12 = 0

5y2 + 15y โ 4y – 12 = 0

5y (y + 3) -4 (y + 3) = 0

(5y โ 4) (y + 3) = 0

Y = 4/5, -3 = 0.8, -3

Canโt be determined

I) 5x2 โ 6x โ 8 = 0

5x2 โ 10x + 4x โ 8 = 0

5x(x โ 2) + 4(x โ 2) = 0

(5x + 4) (x โ 2) = 0

X = -4/5, 2 = -0.8, 2

II) 4y2 + 8y โ 5 = 0

4y2 – 2y + 10y โ 5 = 0

2y (2y โ 1) + 5(2y โ 1) = 0

(2y + 5) (2y โ 1) = 0

Y = -5/2, ยฝ = -2.5, 0.5

Canโt be determined

I) 3x2ย โ 2x โ 56 = 0

3x2ย + 12x โ 14x โ 56 = 0

3x(x + 4) – 14(x + 4) = 0

Canโt be determined

3x โ y = -3 –ร  (1)

5x + 6y = -28 –ร  (2)

By solving the equation (1) and (2), we get,

X = -2, y = -3

X > y

Direction (6-10) :

The cost price of article P

= > 325*(100/130) = Rs. 250

The cost price of article U

= > 275*(100/125) = Rs. 220

Required % = [(250 โ 220)/220]*100 = 14 % more

Manojโs selling price = Rs. 196

Manojโs cost price = 196*(100/140) = Rs. 140

Profit earned by Manoj = 196 โ 140 = Rs. 56

Keerthiโs cost price = Rs. 196

Keerthiโs selling price = 196*(125/100) = Rs. 245

Profit earned by Keerthi = 245 โ 196 = Rs. 49

Required difference = 56 โ 49 = Rs. 7

Cost price of article Q = 144*(100/120) = Rs. 120

Article Qโs marked price = C.P + 60 = 120 + 60 = Rs. 180

Discount = Marked price โ Selling price = 180 โ 144 = Rs. 36

Discount % = (Discount/MP)*100 = (36/180)*100 = 20 %

Cost price of article P = 325*(100/130) = Rs. 250

Cost price of article Q = 144*(100/120) = Rs. 120

Cost price of article R = 192*(100/128) = Rs. 150

Cost price of article S = 196*(100/140) = Rs. 140

The average cost price of the article P, Q, R and S together

= > (250 + 120 + 150 + 140)/4

= > 660/4 = Rs. 165

The profit earned on selling the article P

= > 325*(100/130)*(30/100) = Rs. 75

The profit earned on selling the article T

= > 145*(100/116)*(16/100) = Rs. 20

Required % = (75/20)*100 = 375 %
