Took more than 2 minutes.


Let the cost of the game be x
Gross Profit = .10 x

Original sale prrice = 44

Sale price - cost price = profit
44 - x = .10x
x=40 (profit is 4 $ i.e 10% of 40)

Now the sale price increased to 46

New Profit = 46-40 (cost of game remained same) = 6

So basically we have to find 6 is what % of 400

x/100*40=6

x=15%

TYPO CORRECTION IN BOLD:

Let the cost of the game be x
Gross Profit = .10 x

Original sale prrice = 44

Sale price - cost price = profit
44 - x = .10x
x=40 (profit is 4 $ i.e 10% of 40)

Now the sale price increased to 46

New Profit = 46-40 (cost of game remained same) = 6

So basically we have to find 6 is what % of 40

x/100*40=6

x=15%

let the Cp be X
Gp = 0.1X
Gp = Sp- Cp
0.1 X = 44 - X
1.1X = 44
X = 40
hence Cost price is 40

New selling price is 46

Gross profit = 46- 40 = 6

hence its 6/40 = 15% E

hope its clear . do let me know i u have any doubts

Profit=SP-CP

Profit=0.10CP

original SP=44

Thus, 0.10CP=44-CP

i.e, CP = 40

Now,SP=46 and CP=40

so,profit=6
which is 15% of CP=40

Hence,E

GP = S - C

10X = 44 - 100X

44 = 110X

? = 46 - 100X

Well if 44 is 110X, 46 is 115X

? = 115X - 100X ( Cost remained the same)

? = 15X
