answer-15percent

Hi,
Intial selling price is 44
Intial selling price is 10 percent of cost price.
so Cost price is 10 percent of 44 that is 44-4=40
Now the cost price is 40 and the new selling price is 46.
so gross profit =(46-40)/40 *100
=6/40 *100
=3/2 *10
=15 percent

Hence E is the answer

44-x=.10x x=selling price of game
x=40

46-40=6 dollars gross profit

40 times x/100=6
x=15

Hey, this is very simple...you need not get into any equations to solve.

It is given that 44 is 110% of CP

So obviously 46 will be 46/44 (110%) CP = 115% of CP

Hence 15% will be the profit percentage
