Line Chart Quiz 1

We can represent the 2 pie charts like this

So, profit percentage of MI

=\frac{10*100}{25}
= 40%

So, profit percentage of Godrej

=\frac{15*100}{35}
= 42.85%

So, profit percentage of Micro

=\frac{2*100}{20}
= 10%

So, profit percentage of Apple
=\frac{20*100}{50}
= 40%
So, profit percentage of Jio

=\frac{20*100}{45}
= 44.44%

Hence the answer is Jio

total profit of all the 5 companies is

= 10+15+2+20+20

= 67

Hence the answer is
=\frac{25*100}{67}
= 37.31%
Or, 40%

If the expenditure of Apple increases by 50%,

then the expenditure of Apple will be
=\frac{30*(100+50)}{100}
= 45 Billion Dollars

The previous percentage of Apple is
=\frac{20*100}{50}
= 40%

Let the new income of Apple is x Billion dollars

So as per question
=>\frac{x-45}{x}=0.4
=> x-45 = 0.4x

=> 0.6x=45

So, x=75

So, the answer is
=\frac{(75-50)*100}{50}
= 50%

The total profit of MI, Micro, Jio is

= 10+2+20

= 32 Billion Dollars


The total income of MI, Micro, Jio is

= 25+20+45

= 90 Billion Dollars

So, the answer is
=\frac{32*100}{90}
= 35.55%

Or, approximately 35%

The answer is

= 250+225+200+150+120

= 945

To make the class VIII with 2nd highest strength, the number of students of class VI has to be at most 199.

So, 250-199 = 51 students from class VI has to leave the school

So, the minimum value of x% is

=\frac{51*100}{250}
=20.4%

The total students of this school is

= 250+225+200+150+120

= 945

The students from class VI and class VIII is 250 and 200 respectively

So, the angle made by the student of class VI and VIII combined is
=\left ( \frac{(250+200)*360}{945} \right )^\circ
=171.42^\circ
Or, approximately =171^\circ

As, 80% of the students from class VI pass the exam so,

(100%-80%) or 20% students from class VI will fail the exam and will remain in class VI in 2016.

Hence the total number of students in class VI in 2016 is

=275+\frac{250*20}{100}
=325

The total number of students in class VIII,IX,X is

= 200+150+120

= 470

The average students of class VI and VII is

= (250+225)/2

= 237.5

Hence the answer is

=\frac{470*100}{237.5}
= 197.89%

Or approximately 200%
