established.

6. I. 6x^2-49x+99=0

II. 5y^2+17y+14=0

7. I. 5x^2=19x-12

II. 5y^2+11y=12

8. I. x^3=(1331)^1/3

II. 2y^2-21y+55=0

9. I. 5x=7y+21

II. 11x+4y+109=0

10. I. 2x^2-11x+12=0

II. 2y^2-17y+36=0

**Answers &**

**explanation**

1. 2;

Let the total number of pineapple be x

70/100 x = 350

**x = 350 * 100/70 = 500**

2. 3;

Ratio of their uses = 8 : 10 : 12 = 4 : 5 : 6

**Rent paid by R = 6/15 * 2250 = Rs. 900**

3. 2;

Part of tank filled in 1 hour

1/20 + 1/24 - 1/40 = 15

**Thus, required time for the tank to be filled = 15 hrs.**

4. 2;

15 A = 10 B

3A = 2B Now, B – 10 = 3A – 22

or, B – 10 = 2B – 22 or, (Put 3A = 2B) or, B = 12

A = 2*12/3 = 8

**Required sum = 20**

5. 5;

Speed of train = 450/6 = 75 km/hr

Speed of bike = 75/2 = 37.5 km/hr

**Time taken by bike = 300/37.5 = 8 hour**

6. (2)

6x^2-49x+99=0 = (3x-11) (2x-9)=0

x=11/3, 9/2= 5^2+17y+14=>

(5y+7) (y+2)=> y=-2,-7/5

**x>y**

7.(4)

5x^2-19x+12=0 = x=3,4/5

5y^2+11y=12 = y = 4/5 ,-3

8. (2)

x=11 = 2y^2-21y+55= 0

(2y-11) (y-5)= 0= y=5,11/2

**x>y**

9. (2)

From given equation

x=-7 y=-8

**x>Y**

10 (3)

2x^2-11x+12=> x=3/2,4

2y^2-17y+36=> y=4,9/2
