47 + 6^2 – 5 = 78 - Which type of tiles shows the maximum percentage increase in the price over the given period?
300%200%400%100%500%Option E

The graph shows that the price of M and N type tiles decreases over the period.

Now, for O type tiles the percentage increase from 2006 to 2012 = (200 – 150)/150* 100

For P type tiles the percentage increase from 2006 to 2012 = (300 – 50)/50*100 = 250/50*100 = 500% - In which year is the average price of all four types of tiles the minimum?
20102008200720062011Option B

Average price of all tiles in 2006

= 1/4(50 + 150 + 250 + 300) = 187.5

Average price of all tiles in 2007 =1/4(100 + 200 + 350 + 400) = 262.5

Average price of all tiles in 2008 =1/4(50 + 150 + 200 + 250) = 162.5

Average price of all tiles in 2009 =1/4(100 + 150 + 300 + 350) = 225

Average price of all tiles in 2010 =1/4(100 + 200 + 250 + 300) = 212.5

Average price of all tiles in 2011 =1/4(50 + 100 + 250 + 350) = 187.5

Average price of all tiles in 2012 = 1/4(150 + 200 + 250 + 300) = 225

In 2008, the average price of all four types of tiles is the minimum. - Total price of all four types of tiles in 2012 is what per cent more or less than the total price of all four types of tiles in 2009?
2%4%6%0%7%Option D

Total price of all four types of tiles in 2012

= (150 + 200 + 250 + 300) = 900

Total price of all four types of tiles in 2009 = (100 + 150 + 300 + 350) = 900

Both are equal, so the required percentage is 0%. - What is the ratio of the price of tiles O-Type in 2008 to that of tiles P-Type in 2010?
2:53:51:37:94:5Option E

Required ratio

= Price of O type tiles in 2008/Price of P type tiles in 2010

= 200/250 = 4 : 5 - Which type of tiles shows the maximum average price over the years?
N-TypeP-TypeCannot be determined.M-TypeNone of theseOption A

Average price of M-Type during 2006 to 2012

= 1/7(250 + 400 + 50 + 150 + 200 + 50 + 150) = 1250/7 = 178.57

Average price of N during 2006 to 2012 = 1/7{300 + 350 + 250 + 350 + 300 + 350 + 250) = 2150/7 = 307.14

Average price of O during 2006 to 2012 = 1/7(150 + 100 + 200 + 300 + 100 + 250 + 200) = 1300/7 = 185.714

Average price of P during 2006 to 2012 = 1/7 (50 + 200 + 150 + 100 + 250 + 100 + 300) = 164.28

Thus, N type of tiles’ show the maximum average price during 2006 to 2012.
