Direction (1-5) :

I) 12x2 + x โ 88 = 0

12x2 – 32x + 33x โ 88 = 0

4x (3x โ 8) + 11(3x โ 8) = 0

(4x + 11) (3x โ 8) = 0

X = -11/4, 8/3 = – 2.75, 2.667

II) 15y2 โ 34y โ 72 = 0

15y2 + 20y โ 54y โ 72 = 0

5y (3y + 4) – 18(3y + 4) = 0

(5y โ 18) (3y + 4) = 0

y = 18/5, -4/3 = 3.6, -1.33

Canโt be determined

I) 18x2 + 24x โ 24 = 0

18x2 + 36x โ 12x – 24 = 0

18x(x + 2) – 12(x + 2) = 0

(18x โ 12) (x + 2) = 0

X = (12/18), -2 = 0.667, -2

II) 16y2 + 36y โ 36 = 0

16y2 + 48y โ 12y – 36 = 0

16y(y + 3) – 12(y + 3) = 0

(16y โ 12) (y+3) = 0

Y = 12/16, -3 = 0.75, -3

Canโt be determined

I) 6x2 – 39x + 45 = 0

6x2 – 30x โ 9x + 45 = 0

6x (x โ 5) – 9(x โ 5) = 0

(6x โ 9) (x โ 5) = 0

X = 9/6, 5 = 1.5, 5

II) 9y2 – 24y + 16 = 0

9y2 – 12y โ 12y + 16 = 0

3y (3y โ 4) – 4(3y โ 4) = 0

(3y โ 4) (3y โ 4) = 0

Y = 4/3, 4/3 = 1.33, 1.33

X > y

I) x3 + 34 รท 16 ร 43 = 836

X3 + (81/16)*64 = 836

X3 + 324 = 836

X3 = 512

X = 8

II) y2 โ 20y + 99 = 0

(y โ 9) (y โ 11) = 0

Y = 9, 11

X < y

8x + 3y = 39 โ (1)

3x + 2y = 19 โ (2)

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

X = 3, y = 5

X < y

Direction (6-10) :

Aโs initial investment = 2*Qโs investment = 2*25000 = Rs. 50000

The share of P, S and A,

= > [30000*4 + 40000*8]: [45000*12]: [50000*8]

= > [120000 + 320000]: [540000]: [400000]

= > 440000: 540000: 400000

= > 22 : 27 : 20

69โs = 103500

1โs = 1500

The share of A = 20โs = Rs. 30000

The initial investment of B = (45000/3)*2 = Rs. 30000

The initial investment of M = (125/100)*60000 = Rs. 75000

The share of S, B and M,

= > [45000*12]: [30000*12]: [75000*9]

= > 540000: 360000: 675000

= > 12: 8: 15

8โs = 36000

1โs = 4500

Total profit = 35โs = Rs. 157500

The share of Q, S, U, C and D,

= > [25000*12]: [45000*8 + 40000*4]: [40000*8 + 50000*4]: [2x*7]: [3x*7]

= > 300000: 520000: 520000: 14x: 21x

According to the question,

= > (520000/21x) = (104/63)

= > x = 15000

The initial investment of C = 2x = Rs. 30000

The total investment of P and R

= > 30000 + 50000 = Rs. 80000

The total investment of Q and S

= > 25000 + 45000 = Rs. 70000

Required % = (80000/70000)*100 = 114 %

Nโs initial investment = 40000*(130/100) = Rs. 52000

The share of R, U and N,

= > [50000*2]: [40000*2]: [52000*2]

= > 25: 20: 26

71โs = 142000

1โs = 2000

The share of U = 20โs = Rs. 40000
