Hi All,
I'm a big fan of TESTing THE ANSWERS on this question, but it can also be solved Algebraically, using a 'system' of equations:
T = price of adult fare
F = cost of reservation charge
Adult Ticket = T + F
Kid's Ticket = (T/2) + F
1 reserved Adult Ticket = T + F = 216
1 Adult + 1 Kid = (3T/2) + 2F = 327
From here, you have two variables and two unique equations, so you can solve for both variables. The question asks us for the value of T.
[(3T/2) + 2F] - [T + F] = 327 - 216
T/2 + F = 111
(T + F) - (T/2 + F) = 216 - 111 = 105
T/2 = 105
T = 210
Final Answer:
GMAT assassins aren't born, they're made,
Rich
