**Directions(1-5):** Find the relationship between x and y and choose a required option.

- I. x^2 â€“ 87x -270 = 0

II. 7y^2 â€“ 11y -18 = 0y>xx>yx=y or relation cannot be established.y>=xx>=yOption C

I. x^2 â€“ 87x -270 = 0

x^2 -90x + 3x â€“ 270 =0

=> x = 90,-3

II. 7y^2 â€“ 11y -18 = 0

7y^2 -18y +7y -18=0

=> y = 18/7, -1

x=y or relation cannot be established. - I. 4x^2 + 23x + 15 = 0

II. 4y^2 â€“ 11y + 6 = 0y>xy>=xx>yx>=yx=y or relation cannot be established.Option A

I. 4×2 + 23x + 15 = 0

4x^2 + 20x + 3x + 15 = 0

=> x = -5, -3/4

II. 4y2 â€“ 11y + 6 = 0

4y^2 â€“ 8y â€“ 3y + 6 = 0

=> y= 3/4, 2

y>x - I. 55x^2 – 495x +1100 = 0

II. 5y^2 + 10y -120 = 0x=y or relation cannot be established.y>=xx>=yx>yy>xOption C

I. 55x^2 – 495x +1100 = 0

55x^2 â€“ (220+275)x â€“ 1100 = 0

=> x = 4,5

II. 5y^2 + 10y -120 = 0

5y^2 +30y â€“ 20y â€“ 120 = 0

=> y = -6,4

x>=y - I. x^2 â€“ 87x -270 = 0

=> x = 90,-3

II. 7y^2 â€“ 11y -18 = 0

7y^2 -18y +7y -18=0

x=y or relation cannot be established. - I. 9x^2 – 94.5x + 243 = 0

II. 4.5 y^2 â€“ 13.5y – 486=0y>xy>=xx>yx=y or relation cannot be established.x>=yOption D

I. 9x^2 -94.5x + 243 = 0

9x^2 â€“ (54+40.5)x + 243 =0

=> x = 6,4.5

II. 4.5 y^2 â€“ 13.5y -486=0

4.5y^2 â€“ 54y + 40.5y â€“ 486=0

=> y = 12, -9

x=y or relation cannot be established. - What is the percentage rise in the population of City C from 2010 to 2012?
41.2%30.5%25.12%33.33%50.12%Option D

Required %

= [(6.4-4.8)/4.8]*100 = 33.33% - The literate population of City E in the year 2012 is approximately what percentage more than its literate population in 2010?
15.5%22.5%40.2%37.3%20.5%Option D

City E (2010) = 5.5*(67.7/100) = 3.7235 lakh

City E(2012) = 7.2*(71/100) = 5.112 lakh

Required % = [(5.112 â€“ 3.7235)/3.7235]*100 = 37.3% - What is the difference between the Literate population and illiterate population of City D in the year 2010? (in lakh)
1.500 lakh1.250 lakh2.115 lakh1.508 lakh5.002 lakhOption D

Total population = 5.2 lakh

Percentage of literate population = 64.5%

Percentage of illiterates = 100-64.5 = 35.5%

Difference = 64.5 â€“ 35.5 = 29%

Required answer = 5.2*(29/100) = 1.508 lakh - What is the difference between the total illiterate population of City G and City F in the year 2010? (in lakh)
0.1700 lakh0.1437 lakh0.4300 lakh0.7500 lakh0.1220 lakhOption B

Required difference

= 7.5*(100-68.9)/100 â€“ 6.4*(100-65.8)/100 = 0.1437 lakh - What is the total literate population of City A in the year 2010 and 2012 together (in lakh)?
5.445 lakh3.450 lakh5.000 lakh6.444 lakh5.005 lakhOption A

Literate population of City A in 2010

= 3.6*(57.8/100) = 2.0808 lakh

Literate population of City A in 2012 = 5.4*(62.3/100)

= 3.3642 lakh

Total = 2.0808 + 3.3642 = 5.445 lakh

**Directions(6-10):** Following line-graph shows the population of seven cities (in lakh) and the table shows the percentage of literate population in these cities.

Thanks for this excellent article. One other thing is that most digital cameras come equipped with a zoom lens that allows more or less of the scene to get included by means of ‘zooming’ in and out. Most of these changes in {focus|focusing|concentration|target|the a**** length tend to be reflected inside viewfinder and on substantial display screen right on the back of the specific camera.
