Answer:
x=3
Step-by-step explanation:
0=x-3
-x=-3
x=3
Lets say the final price of the bike is SP plus 13% VAT. So:
1.13 * SP = 6356.25
SP = 5625
Now SP was after 10% discount on Original Price, say MP. So:
0.9 * MP = 5625
MP = 6250
Therefore, the percent of Marked Price above Cost Price is:
(6250 - 5000) * 100/5000 = 25%
