Data Interpretation - Pie Charts - Discussion

The pie chart shows the distribution of New York market share by value of different computer companies in 2005.

The pie chart shows the distribution of New York market share by volume of different computer companies in 2005.

Number of units sold in 2005 in New York = 1,500

Value of units sold in 2005 in New York = US $1,650,000.

1. 

For the year 2005, which company has realised the lowest average unit sales price for a PC ?

[A]. Commodore
[B]. IBM
[C]. Tandy
[D]. Cannot be determined

Answer: Option D

Explanation:

Although it seems to be Commodore, the answer cannot be determined due to the fact that we are unaware of the break-up of the sales value and volume of companies compromising the other categories.

Pardon,

Why no 1 is D -Cannot be determined? what is the different with no 3? It looks like the way to find out result similar.

We can find individual unit sale price of company by given values (total units and total values) I don't understand why value is undetermined.

Swapnil said: (Jan 8, 2014)  
We can find the individual values using; value/units = price /unit.

It is not clear please explain.

Harsh Verma said: (Jun 13, 2014)  
We can find
=(value * per company percentage in value pie chart)/(volume * percentage company in volume chart).

By this we get individual sale for all the companies and we able to compare.

So why answer be undetermined?

Rishabh said: (Sep 22, 2014)  
Its answer would come as we solve question 3 here.

Let's suppose a company has manufactured 100 PCs (say).

We do not know how many out of 100 are sold and at what price.

Therefore, we cannot determine the average unit sales price.

Subhash said: (Nov 27, 2014)  
This question is same as (similar) to question no 4 of this pie chart. When we can find the answer of that question then I don't understand why are you saying "we don't know out of 100 how many sold and at what price".

What is distribution by value and by volume?

Ravi said: (Feb 24, 2015)  
The answer is commodore. Dont know why they have written that the answer can't be determined. Its share can be calculated which is 8% of the total share value.

Similarly no. of units can be calculated which is 34% of 1500. So we can easily calculate the avg value by dividing by no. of units and the answer will be 258.82.

Here volume and value of "Other" category is shown. But "OTHER" section may consist of computers of different company and different value. So we can't find out value of individual unit of "OTHER" section.

Shankar said: (Sep 22, 2015)  
Do not understand why it cannot be determined? Price of a single unit can be easily determined and compare.

Sameer said: (Nov 25, 2015)  
Read the question twice because, it is questioning about lowest average unit sale.

Varun said: (Jul 2, 2016)  
@ All.

The procedure for finding a single unit sales value is to VALUE by VOLUME.
But as others section is unknown (it can be anything) we might have the lowest value from any of those companies hence commodore can't be concluded as the lowest.

Harry said: (Nov 30, 2016)  
I think as question 4 we can find the avg unit sales value for each company then we can compare them which one is lowest. Am I right?

Inayat said: (Dec 7, 2016)  
The Answer is a commodore. Your calculation is correct @Ravi.

If A is not the correct answer, please explain in detail.

I'm confused there's like two 6 percent in the 2005 pie chart why is it going with commodore?

Lakhwinder Singh said: (Dec 26, 2017)  
Unable to understand it. Please someone help me.

Raj said: (Feb 5, 2018)  
I don't understand. Please help me.

Supratik said: (Feb 11, 2018)  
I agree with @Shital.

Because in order to calculate anything so precise such as lowest average unit, we need to have full information about the entire set, which, in this case, do not have.

Nicolus said: (Feb 22, 2018)  
At first, I went to Commodore, but once, reading Varun comment, I got it. Just tricky with the word "others".

Niranjan said: (Sep 1, 2018)  
The answer is COMMODORE,

Because if we calculate for IBM PC in average unit sale price in question 3 of this section, which answer is $3080 per unit.

Same is for all, where we found that lowest is Commodore ($259 per unit).

Shubhankar Singh Bhadouriya said: (Dec 27, 2019)  
Yes, the answer can easily determine because it was given there in percentage (8%...).
We only have found out 8% of the total price amount.

Please correct the above answer.

Kishor said: (May 9, 2020)  
Answer should be A.

Satya Jeet Verma said: (Aug 25, 2020)  
Here we can not determine because we only know how many units are sold but don't know at what price it is sold because here cumulative price is given but individual company laptop price is not given.

Yuki said: (Aug 28, 2020)  
Which is the correct answer, A or D? Please tell me.

Sanket Sharma said: (Feb 25, 2021)  
The procedure for finding a single unit sales value is to VALUE by VOLUME.

But as another section is unknown (it can be anything) we might have the lowest value from any of those companies hence commodore can't be concluded as the lowest.

Sia said: (Aug 20, 2021)  
What's meant by "value", isn't value the price amount, like a monetary valuation of the companies? Anyone explain me.
