Bar Graph Quiz 1

The total production of pencil in these 5 years is

= 75+80+65+53+93

= 366 thousands

 

Hence the answer is

= 366/5

= 73.2 thousands

Average selling prices:

In the year 2010 = 10/-

In the year 2011 = \frac{10\times 110}{100}[/layex] = 11/-

In the year 2012 = \frac{11\times 110}{100}[/layex] = 12.1/-

In the year 2013 = \frac{12.1\times 110}{100}[/layex] = 13.31/-

In the year 2014 = \frac{13.31\times 110}{100}[/layex] = 14.641/-

 

So the total income is

= (75×10+ 80×11+ 65×12.1 + 53×13.31 + 93×14.641)×1000

= 3778113/-

Hence the average income is = 3778113/5

=755622.6/-

The total production of pencil in these 5 years is

= 75+80+65+53+93 = 366 thousands

Hence the average production = 366/5 = 73.2 thousands

So, the answer is

= 93-73.2 = 19.8

Production in 2010 = 75 thousands

Production in 2014 = 93 thousands

Hence the answer = \frac{(93-75)\times 100}{75} = 24%

The average production of the year 2013 and 2014 = (53+93)/2

= 73 thousands

So, from 2011 to 2014 there are 2 years (2011, 2014) in which the production of pencils was more than the average production of pencils of the years 2013,2014.

We can represent the chart like this:



 

So the answer is

= (1400+675+360)/3 = 811.67 (Thousand rupees)

We can represent the chart like this:



If selling price per bottle of Mirinda increased by 20%

Then the selling price per bottle will be = (20 × 6)/5 = 24

The revenue earned by merinda will be = 24 × 18 = 432

As the revenue earned by Pepsi is 875 thousand rupees,

So the answer = \frac{432\times 100}{875} = 49.37

So, approximately 50 %.

The amount of all the bottles are

= 35+40+25+12+18 = 130 (in thousands)

Number of Limca bottle is 40

Hence the answer is

= 40/130 = 4/13

or, 8/26 [by multiplying numerator and denominator by 2]

Total number of bottles is

= 35+40+25+12+18 = 130 (in thousands)

 

Hence the answer is

=\frac{[(25\times 35)+(35\times 40)+(27\times 25)+(22\times 12)+(20\times 18)]\times 1000}{130\times 1000}

= 27.49 = 27.50/- approx.

We can represent the chart like this:



So, on that day the revenue generated by merinda is 264

And the revenue generated by Limca is 1400

Hence the answer = \frac{264\times 100}{1400}

= 18.86 %

Hence, the answer is approximately 20%
