­A certain pizzeria has more than fifty types of pizzas on its menu.

Is there an alternate way to solve this using just numbers?

As per question stem:
pizzeria has more than fifty types of pizzas on its menu, chart shows the revenue share of its four most popular pizza types.
Qns asks: Which was their best-selling pizza last month in terms of number of pizzas sold?
How can we rule out any other pizza which may be higher priced but selling in more numbers from Others (62%) of the pie.?­
I guess we need to assume here that most popular means selling in max quantity..
 

 
@vivekthesmarty ­Correct, "most popular" does mean the pizza types sold in the highest quantities.

Interesting discussion. ­Let me add to it.
@vivekthesmarty, 
As opposed to what? generating the highest revenue? 

Even if we take "most popular" to mean "generating the highest revenue", it won't change the answer.

If the figure shows the 4 highest revenue shares of all 50 pizzas,
1. Tomato Blast has the highest revenue share, and, according to statement 2,
2. Tomato Blast was the lowest-priced pizza type on the whole menu, i.e. out of all 50 types of pizza.

'Highest revenue' and 'lowest price' combined would mean the Tomato Blast was sold in the highest quantity - out of all 50 types.

Makes sense?


Tell me if you had some other interpretation of "most popular".­­­­­

­Statement (1) only tells us pepperoni pizza had the most customers who ordered at least one. It doesn't necessarily tell us how many pepperoni pizzas were sold in total.

=> Not sufficient


Statement (2) clarifies that Tomato Blast is the lowest-priced pizza and has the highest revenue.

Number sold = Revenue / Price per pizza

==> Tomato Blast must have the highest quantity sold
==> Tomato Blast is the best seller

==> Sufficient

Answer is B

We'd have to "assume" that Tomato Blast with 14% revenue has the highest revenue in order to get the answer as 'B'. Otherwise the answer should be 'E'

Four most popular pizzas? popular in terms of what? In terms of internet reviews? in terms of number of social media post about them?

What if in the 'others' section, which is 62% of the revenue, let's say we have 45 types of pizzas with 1% revenue, then the 46th type of pizza will have to contribute to 17% of the revenue.

This 46th type of pizza may not be as popular as the other 4 four, but according to our assumptions above, it can contribute 17% of the review.

Now Tomato Blast is the cheapest followed by VegChese, then let's say this 46th is the 3rd cheapest or at 2nd cheapest place along with VegCheese.
Say Tomato Blast is $0.875, VegCheese is $1.00, and this 46th type is priced at $1.00. The revenue can be taken as $1000

Tomato Blast would have contributed $140 with 160 numbers (160*$0.875 = $140)
VegCheese would be at $50 with with 50 numbers
46th type would have $170 with 170 number.
In this example this 46th type tops in terms of number of pizza sold. Again, 46th may not be as popular as other 4, but last month people secretly ordered 46th (which has pineapples on it) because they experimented with pineapples on pizza but won't admit openly that they liked it the most.
