A car dealership sold two cars: the first car at a 10% profit and the second car at a 10% loss, which gave them an overall profit margin of 5% from these two sales. If the dealership's total profit was $1000, what was the sale price of each car?
A) $5,000 and $1,000
B) $9,000 and $5,000
C) $11,000 and $9,000
D) $15,000 and $5,000
E) $20,000 and $10,000
Again - I struggle to solve this question using back-solving as described in gmatclub test m03. Any idea how to do it algebraically?
I tried doing it this way but got stuck:
Let say Cost Price of 1st car = x & Cost Price of 2nd car = y
SP of 1st car = 1.1x -----------------------------------------(1)
SP of 2nd car = 0.9 y ----------------------------------------(2)
Profit = S.P - C.P
I can use
(1.1. x - x ) + (0.9y -y) -----------> But this is not possible. Please help.
