Moderator Joined 30 Aug 2017 Posted: 772 messages Followed by: 6 members let the cost of a hamburger be 'ham', the cost of a fresh fries be 'fri' and the cost of coleslaw be 'col'. from the question, ham + col=$3.59 ------(i)
ham + fri= $4.40 ---------(ii) fri= 2*col.= 2col --------(iii) from i, ham =$3.59- col
from ii, ham = $4.40-fri since the price of ham in both is the same, then ham= 3.59-col = 4.40-fri 3.59-col = 4.40 - fri fri-col = 0.81 but from equation iii, col= fri/2 therefore, $$fri-\frac{fri}{2}=0.81$$ $$2fri-fri=1.62$$ $$fri=1.62$$ $$Therefore,\ french\ fries\ \cos t=1.62$$ ### GMAT/MBA Expert GMAT Instructor Joined 04 Oct 2017 Posted: 551 messages Followed by: 11 members Upvotes: 180 dunkin77 wrote: Hello The answer is E) but my answer for French fries was$1.62....
