“If m is three times n, and if 2n + 3 is 20% of 25, what is the value of m?”- is a topic of the GMAT Quantitative reasoning section of GMAT. This question has been taken from the book “GMAT Quantitative Review”. To solve GMAT Problem Solving questions a student must have knowledge about a good amount of qualitative skills. The GMAT Quant topic in the problem-solving part requires calculative mathematical problems that should be solved with proper mathematical knowledge.

Answer:

Approach Solution 1

m is three times n: m = 3n
2n + 3 is 20% of 25: 2n + 3 = 0.2 * 25
So, n = 1
Hence, m = 3 * 1 = 3

Correct option: C

Approach Solution 2

20% of 25 is 5
So, 2n + 3 = 5
2n + 2
n = 1
We know m = 3n and n = 1
Hence, m = 3

Correct option: C
