in this series, one of our most experienced GMAT tutors, John Easter, applies useful strategies to answer questions from the 2018 Official Guide.
Problem #167 of the 2018 Official Guide to the GMAT states that four extra-large sandwiches of exactly the same size were ordered for m students where m>4.

This blog post relates to question #116 from the Official Guide for GMAT Review, 2017.
