Your question was - If the cost of one dozen of apples is $96 and the cost of 1 dozen of bananas is $36, then find the average cost of 18 apples and 18 bananas? A few days ago I take part an exam where I have faced this GMAT questions and my answers option were - a. $3 b. $8 c. $12 d. $5.5 e. None of the above I have answered as my Correct answer is =  d Because of this following Explanation: According to the question, The cost of one dozen of apples = $96.....i The cost of 1 dozen of bananas = $36....ii We know hat, one dozen = 12 units ∴ From statement (i) we can say that, 12 apples = $96 ∴ Cost of 1 apple = 96/12 = $8...iii ∴ Cost of 18 apples = 18*8 = $144.....iv Similarly, from statement (ii) we can say that, 12 bananas = $36 ∴ Cost of 1 banana = 36/12 = $3.....v ∴ Cost of 18 bananas = 18*3 = 54......vi Hence, the total cost of 18 apples and 18 bananas = $144 + $54 = $198 But, we have to find the average cost of 18 apples and 18 bananas = 198/36 = 5.5 Hence, the correct answer is option d. Hope you have got your answer. Thanks.
