** Directions (1-5): In each of these questions, two equations are given. You have to solve these equations and find out the values of x and y and give answer **

**3x**^{2}– 14x + 8 = 0, 3y^{2}+ 2y – 8 = 0

A) x > y

B) x < y

C) x ≥ y

D) x ≤ y

E) x = y or relationship cannot be determined**E) x = y or relationship cannot be determined**

Explanation:

3x^{2}– 14x + 8 = 0

3x^{2}– 12x – 2x + 8 = 0

3x(x-4) – 2(x-4) = 0

x = 2/3, 4

3y^{2}+ 2y – 8 = 0

3y^{2}+ 6y – 4y – 8 = 0

3y(y+2) – 4(y-2) = 0

y = 4/3, 2**8x**^{2}+ 6x = 5, 12y^{2}– 22y + 8 = 0

A) x > y

B) x < y

C) x ≥ y

D) x ≤ y

E) x = y or relationship cannot be determined**D) x ≤ y**

Explanation:

8x^{2}+ 6x – 5 = 0

8x^{2}+ 10x – 4x – 5 = 0

2x(4x+5) – (4x+5) = 0

x = 1/2 , -5/4

12y^{2}– 22y + 8 = 0

12y^{2}– 16y – 6y +8 = 0

4y(3y-4) – 2(3y-4) = 0

y = 1/2, 4/3**x = √172, y**^{2}– 29y + 210 = 0

A) x > y

B) x < y

C) x ≥ y

D) x ≤ y

E) x = y or relationship cannot be determined**B) x < y**

Explanation:

x = √172 = 13.1

y^{2}– 29y + 210 = 0

(y-15)(y-14) = 0

y = 14,15**7x + 16y = 75, 6x – 8y = -9**

A) x > y

B) x < y

C) x ≥ y

D) x ≤ y

E) x = y or relationship cannot be determined**B) x < y**

Explanation:

Solve the equations, x = 3, y = 27/8**x**^{2}+ 11x + 30 = 0, y^{2}+ 12y + 36 = 0

A) x > y

B) x < y

C) x ≥ y

D) x ≤ y

E) x = y or relationship cannot be determined**C) x ≥ y**

Explanation:

x^{2}+ 11x + 30 = 0

(x+6)(x+5) = 0

x = -5, -6

y^{2}+ 12y + 36 = 0

(y+6)^{2}= 0

y = -6

** Directions (Q. 6-10): Study the following graph and answer the following questions. **

**In which year was the sale of ‘Pep-up’ the maximum?**

A) 2011

B) 2012

C) 2013

D) 2010

E) None of these**D) 2010**

Explanation:

It can be seen in graph that in 2010 it is max.**In the case of which soft drink was the average annual sale maximum in the given period?**

A) Pep-up only

B) Cool-sip only

C) Dew-drop only

D) Cool-sip and Dew-drop

E) None of these**A) Pep-up only**

Explanation:

Add the sales of all dinks individually. The drink which has max in total is the answer.**In the case of Cool-sip drink, what was the percent increase in sale in 2013 over its sale in 2012?**

A) Less than 20

B) 20-25

C) 25

D) 31-35

E) None of these**C) 25**

Explanation:

25-20/20 * 100 = 25%**What was the approximate per cent increase in sale of all drinks in 2013 over its sale in 2010?**

A) 51%

B) 45%

C) 22%

D) 32%

E) None of these**D) 32%**

Explanation:

Sales in 2013 = 30+25+20 = 75

Sales in 2010 = 15+7+35= 57

So required % = 75-57/57 * 100 = 32%**What was the approximate per cent drop in sale of Pep-up in 2011 over its sale in 2010?**

A) 5

B) 12

C) 14

D) 20

E) None of these**C) 14**

Explanation:

35-30/35 * 100
