Let the price of each printer be x.
and price of each scanner be y.
FOR 3 printer & 1 scanner , Total Price = 3x + y
Statement 1 :- The total price of the printers and the scanner was $1,300.
So \(3x + y = 1300\)
We have only one equation. We can't get unique value of y.
Hence insufficient.
Statement 2 :- The price of each printer was 4 times the price of the scanner.
This is : \(x = 4y\)
This is also insufficient to find the price of the scanner.
Statement 1 and Statement 2 :-
Gives us two equation. \(3x + y = 1300\) and \(x = 4y\)
Solving this would give us the price of the scanner.

Solution
Given:
- • A company bought 3 printers and 1 scanner
To find:
- • The price of the scanner
Analysing Statement 1
- • As per the information given in statement 1, the total price of the printers and the scanner was $1300
- o From this statement, we can’t find out the individual price of a scanner
Hence, statement 1 is not sufficient to answer
Analysing Statement 2
- • As per the information given in statement 2, the price of each printer was 4 times the price of scanner
• If we assume the price of the scanner to be p, then price of each printer will be 4p
- o Hence, total cost of 3 printers and 1 scanner = 3 * 4p + p = 13p
Hence, statement 2 is not sufficient to answer
Combining Both Statements
If we combine the data from both the statements, we can say:
- • 13p = 1300
From this we can find out the value of p
Hence, the correct answer is option C.
Answer: C

Let P = price of ONE printer
Let S = price of ONE scanner
Target question: What is the value of S?
Statement 1: The total price of the (3) printers and the (1) scanner was $1,300.
So, we can write: 3P + S = 1300
Does this provide enough information to determine the value of S?
No.
There are several cases that satisfy statement 1. Here are two:
Case a: P = 400 and S = 100. Notice that these values meet the condition that 3P + S = 1300. In this case, the answer to the target question is S = 100
Case b: P = 300 and S = 400. Notice that these values meet the condition that 3P + S = 1300. In this case, the answer to the target question is S = 400
Since we cannot answer the target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: The price of each printer was 4 times the price of the scanner.
So, we can write: P = 4S
There are several cases that satisfy statement 2. Here are two:
Case a: P = 400 and S = 100. Notice that these values meet the condition that P = 4S. In this case, the answer to the target question is S = 100
Case b: P = 800 and S = 200. Notice that these values meet the condition that P = 4S. In this case, the answer to the target question is S = 200
Since we cannot answer the target question with certainty, statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined
Statement 1 tells us that 3P + S = 1300
Statement 2 tells us that P = 4S
Since we COULD solve this system of equations for P and S, we COULD answer the target question (although we would NEVER waste our valuable time actually solving the system on test day.)
Since we COULD answer the target question with certainty, the combined statements are SUFFICIENT
Answer: C
ASIDE: If we solve the system, we get P = $400 and S = $100

Brent

I'd like to add that the OG solution to this question is quite eloquent in that it doesn't assume that the printers are all equal in price until it tests evidence (2).
OG lays out the solution like this:
(1) \(P1 + P2 + P3 + S = $1,300\)
(2) \(P1 = P2 = P3 = 4S\)
Combined:
\(4S + 4S + 4S + S = $1,300\)
This may seem extremely obvious to some people and may not be helpful for everyone, but especially for GMATers that are prone to rushing and making silly mistakes (like me), I think this approach emphasises that we MUST NOT take things for granted and that we MUST pay special attention to nuances of these easy questions, which are worth A LOT of points.

Given, Company bought 3 printer & 1 scanner.
Price of 1 scanner =?
a) total price of 3 printer+1 scanner =$1300 (multiple values possible for scanner)
Not sufficient (Cancel DA)
b)price of printer = 4*price of scanner (Multiple values possible)
Not sufficient (Cancel B)
together a*b, two equation two variable. Sufficient to calculate price of 1 scanner.

Solution:
Question Stem Analysis:
We need to determine the price of the scanner, given that the company bought 3 printers and 1 scanner. We can let the price of the scanner be s and the price of a printer be p. We need to determine the value of s.
Statement One Alone:
With the information in statement one, we can create the equation:
3p + s = 1,300
With one equation and two variables, we can’t determine the value of s (or p). Statement one alone is not sufficient.
Statement Two Alone:
With the information in statement two, we can create the equation:
p = 4s
Again, with one equation and two variables, we can’t determine the value of s (or p). Statement two alone is not sufficient.
Statements One and Two Together:
With the two statements, we see that:
3p + s = 1,300
and
p = 4s
Substituting 4s for p in the first equation, we have:
3(4s) + s = 1,300
13s = 1,300
s = 100
We see that the price of the scanner is $100.
Answer: C
