The figure above shows the cost of joining and buying music from a music subscription service. What does the y-intercept of the line most likely represent?

A
The cost per song

B
The cost to join the service

C
The cost of buying 20 songs

D
The cost of 20 subscriptions to the service

Solution

When no. of songs are 0 then cost is 20$. This means the cost of joining the service is 20$.
Hence, the y-intercept (i.e. 20) of the line represent the cost to join the service.
So, the answer is option (B).
Question 3

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 $$135^o$$.
Question 4

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 $$=\cfrac { 31}{ 100 }\times 27300 =8463.$$

In which pair of years was the number of candidates qualified, the same?

A
1995 and 1997

B
1995 and 2000

C
1998 and 1999

D
Data inadequate

Solution

The graph gives the data for the percentage of candidates qualified to appeared and unless the absolute values of number of candidates qualified or candidates appeared is know we cannot compare the absolute values for any two years.
Hence, the data is inadequate to solve this question.

What was the percentage increase in imports from 1997 to 1998 ?

A
72

B
56

C
28

D
Data inadequate

Solution

The graph gives only the ratio of imports to exports for different years. To find the percentage increase in imports from 1997 to 1998, we require more details such as the value of imports or exports during these years.
Hence, the data is inadequate to answer this question.
