Each week Manhattan GMAT posts a GMAT question on our blog and follows up with the answer the next day. Are you up for the challenge?
Several friends in a dinner group decide to contribute equally to the purchase of a $36 gift. How many people are in the group?
(1) The number of people in the group is equal to the size of each person’s contribution, in dollars.
(2) If three more people joined the group, each person’s individual contribution would fall by $2.
