If we want to know the total revenue that the theater received, we need to know:
(# of full-price tickets)x(full-ticket price) + (# of reduced-price tickets)x(reduced-ticket price)

I'll assign the following variables for clarity:
number of full-price tickets = F
price of each full-ticket = f
number of reduced-price tickets = R
price of each reduced-ticket = r
Revenue = (F)(f) + (R)(r)

In order to answer the question, we'd need values for each of these variables: F, f, R, and r.

We're given the total # of tickets, so we know that F + R = 400. If we knew a proportion between F and R, we could infer the values. We would still need actual values for f and r.

Target question: what are the values of F, f, R, and r?

(1) The number of tickets sold at the full price was 1/4 of the total number of tickets sold.
This allows us to infer that F = 100 and R = 300. We still don't know the prices of each ticket, so we don't know total revenue. Insufficient.

(2) The full price of a ticket was $25. With this statement alone, we know that f = 25, but we do not know how many of each ticket was sold, or the price of reduced tickets. Insufficient. (1) & (2) together We know that F = 100, f = 25, and R = 300. However, we still don't know anything about the price of reduced tickets, so we don't know the total revenue. Insufficient. The answer is E. _________________ Ceilidh Erickson Manhattan Prep GMAT & GRE instructor EdM in Mind, Brain, and Education Harvard Graduate School of Education Manhattan Prep instructors all have 99th+ percentile scores and expert teaching experience.

Hello, Experts. Can you please share how to solve this problem.
Say the number of tickets sold at full-price = a, thus the number of tickets sold at reduced price = 400 - a

Say the full price = b and the price of the tickets sold at reduced price = c

Total revenue = Revenue from the sale of tickets at full-price + Revenue from the sale of tickets sold at reduced price

= ab + (400 - a)c

If we get the value of a, b and c, we get the answer.

Statement 1: The number of tickets sold at the full price was 1/4 of the total number of tickets sold.

This gives 400 - a = 1/4 of 400 = 100

Thus, a = 300.

We do not yet know the values of b and c, we cannot get the value of Total revenue. Insufficient.

Statement 2: The full price of a ticket was $25. => b =$25.

We do not yet know the values of a and c, we cannot get the value of Total revenue. Insufficient.

Statement 1 & 2:

We still do not have the value of c, we cannot get the value of Total revenue. Insufficient.

The correct answer: E

Hope this helps!

Compare to a similar OG question posted here: http://www.beatthegmat.com/og2016-ds-what-was-the-total-t296245.html#797220

It's worth noting that the GMAT often writes variations on the same prompt!
