I think you can backsolve this oneknight247 wrote:A storekeeper sells an item at a profit of 6%. Had he sold at a loss of 2% he would have earned $4 less. Find the selling price of the item.
(A)49
(B)50
(C)52
(D)53
(E)106
OA is D
Start with C) 52
52 - C/C = 6/100
5200 - 100 C = 6C
C = 49
49 - S (loss) /49 = 2/100
4900 - 100 S(l) = 98
S (loss) = 48.02
52 - 48.02 = 3.98 < 4
so pick a bigger number D) 53
53 - C/C = 6/100
5300 - 100C = 6c
C = 50
50 - S(l)/50 = 2/100
S(l) = 49
53 - 49 = 4
