The table shows the number of cups of four different beverages sold by a coffee shop. What is the angle of sector representing tea in a pie chart?
Beverage
Number of cups
Coffee 60
Tea
75
Hot chocolate
25
Milk
40

A
$$40^o$$

B
$$135^o$$

C
$$108^o$$

D
$$72^o$$

Solution

Given table shows the number of cups sold for four different beverages by a coffee shop.
If the given data is represented in a pie chart, the complete angle of the circle is divided into four parts, each representing the number of cups for a particular beverage.
We know that, the complete angle in a circle is $$360^o$$.
Also, total number of cups in the given data $$=60+75+25+40$$
$$=200$$
Also, number of cups for tea $$=75$$.
Hence, the angle of sector represent tea $$=\dfrac{75}{200}\times 360^o$$.
$$=135^o$$

Hence, the angle of the sector representing tea in the pie chart is $$135^o$$.

The pie-charts show the distribution of students of IIT's in seven different companies.
How many of TATA and BIRLA are students from IIT?

A
$$4641$$

B
$$3822$$

C
$$8420$$

D
$$8463$$

Solution

Total % in TATA & BIRLA $$=17+14=31\%$$
Number of people from $$=\cfrac { 31}{ 100 }\times 27300 =8463.$$
Question 5
1 / -0

Which experiment has equally likely outcomes?

A
Choose a number at random from $$1$$ to $$7$$

B
Toss a coin

C
Roll a die

D
All the above

Solution

A) Experiment: Choose a number of at random from $$ 1 $$ to $$ 7$$
$$\Rightarrow $$ All the 7 outcomes are equally likely.

B) Experiment: Toss a coin
$$\Rightarrow$$ Either the outcome is head or its tail. Both are equally likely.

C) Roll a die
$$\Rightarrow$$ All the six outcomes are equally likely.

Hence all the above experiments have equally likely outcomes.

A
90 degrees

B
120 degrees

C
220 degrees

D
360 degrees

E
180 degrees
Question 7
1 / -0

If 3,750 2-door sedans were sold in 1999, then how many 4-door sedans were sold in 1999 by XYZ Auto Company?

A
3,578

B
4,950

C
5,120

D
5,670

E
5,845
Question 8
1 / -0

Consider the following statements in respect of a histogram:
1. The histogram consists of vertical rectangular bars with a common base such that there is no gap between consecutive bars.
2. The height of the rectangle is determined by the frequency of the class it represents.
Which of the statement given above is/are correct?

A
$$1$$ only

B
$$2$$ only

C
Both $$1$$ and $$2$$

D
Neither $$1$$ nor $$2$$
Solution
The above graph shows a histogram.
The histogram consists of vertical rectangular bars with a common base such that there is no gap between consecutive bars.
The area of the rectangle represents the frequency of the corresponding class interval unlike the bar graph where the height represents the frequency
$$\Rightarrow$$ Only statement 1 is true
