e) If x = y or the relation cannot be established

1)

I) 8x – 3y = -4

II) 9x – 4y = -2

2)

I) x2 + 5x – 126 = 0

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

b) 78 %

c) 143 %

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 %
