1) If x > y
2) If x >= y
3) If x < y
4) If x <= y
5) If x = y or the relationship can't be established.

1.
I. 14x^2 + 17x - 6 = 0
II. 6y^2 - 13y + 5 = 0

2.
I. x = √7
II. 6y^2 - 7y - 20 = 0

3.
I. 3x^2 + 8x - 35 = 0
II. y^2 - 2y - 48 = 0

4.
I. x^2 - 23x + 132 = 0
II. y = 3√1331

5.
I. 7x - 5y = 64
II. 4x + 3y = 19

4. 2
5. 1

6. 4
Quantity of Guava available at vendor A
= 2400 × 10/100 = 240 kg
Quantity of Guava at available at vendor B
= 2000 × 16/100 = 320 kg
So, required difference = 320 – 240 = 80 kg

7. 2
At vendor A,
Cost of Mango = 130 × 2400 × 24/100 = Rs. 74880
Cost of Apple = 140 × 2400 × 16 /100 = Rs. 53760
Cost of Orange = 80 × 2400 × 20/100 = Rs. 38400
So, required ratio = 7488 : 5376 : 3840= 39 : 28 : 20
128. 4; Quantity Mango available at vendor B
= 2000 × 24/100 = 480 kg
Quantity Mango available at vendor A
= 2400 × 24/100 = 576 kg
So, required percentage = 480/576 * 100 = 83%

9. 4
Cost of all fruits available at vendor A
= (2400 × 24/100 × 130 + 2400 × 16/100 × 140
+ 2400 × 10/100 × 68 + 2400 × 20 /100 × 80
+ 2400 × 30/100 × 115)
= 24× [24 × 130 + 16 × 140 + 10 ×68 + 20 × 80 + 30 × 115]
= 24× [3120 + 2240 + 680 + 1600 + 3450] = Rs. 266160
Cost of all fruits available at vendor B
= (2000 × 24/100 × 130 + 2000 × 14/100 × 140 + 2000 ×
16/100 × 68 + 2000 × 20/100 × 80 + 2000 × 26/100 × 115)
= 20[24 × 130 + 14 × 140 + 16 × 68 + 20 × 80 + 26 × 115]
= [3120 + 1960 + 1088 + 1600 + 2990] × 20 = ` 215160
So, required difference = Rs. 51000

10. 5
Quantity of Orange available at Vendor A = 2400 × 20/100 = 480kg
Quantity of Apple available at Vendor B = 2000 × 14/100 = 280 kg
So, required percentage = (480 - 280)/280 * 100 = 71.43%
