An importer wants to purchase N high quality cameras from Germany and sell them in Japan. The cost in Germany of each camera is E euros. He will sell them in Japan at Y yen, which will bring in a profit, given that the exchange rate is C yen per euro. Given the exchange rate of D US dollars per euro, which of the following represents his profit in dollars?
(A) N(YC - DE)
(B) ND(YC - E)
(C) ND[(Y/C) - E]
(D) N[(Y/C) - DE]
(E) ND(Y - E)/CLet us plug in:
N = 4, E = 3, Y = 8, C = 2, D = 2
The exchange rate is 2 yen per euro which means every euro is equal to 2 yen.
Cost 3 x 2 = 6 Yen
Revenue = 8 Yen
Profit per unit = 2 Yen
Total Profit = 2 x 4 = 8 Yen which is equal to 4 Euros
The exchange rate is 2 $ per euro hence the profit is 8 $.
Hence our target is 8:
(A) N(YC - DE) = 4 (16 - 6) ELIMINATED
(B) ND(YC - E) = 8 (16 - 3) ELIMINATED
(C) ND[(Y/C) - E] = 8 (4 - 3) = 8
(D) N[(Y/C) - DE] = 4 ( 4 - 6) ELIMINATED
(E) ND(Y - E)/C[/color] = 8 (5)/(2) ELIMINATED
