Question

Find the cost price where Profit=200, Profit%=10%

Answer 1

Answer:  2000

Use your currency of choice

============================================

Work Shown:

profit percentage = (profit/cost)*100%

10% = (200/c)*100%

(10%)/(100%) = 200/c

1/10 = 200/c

1*c = 10*200 ... cross multiply

c = 2000 is the cost price (of whatever currency you prefer)

Notice that 10% of 2000 is 200. We chop off a 0 at the end when taking 10%. Add on a zero when going in reverse.

200 is 10% of 2000

In other words, the profit (200) is 10% of the cost price (2000).

Answer 2

PA = P% of CP
200 = 10/100 * CP
200*100/10 = CP
2000 = CP
SP = 2200
