Step-by-step explanation:

METHOD 1

Find the amount of profit and add with CP

CP = 12000

Profit% = 15%

$Profit\% = \frac{Profit \times 100}{cp} \\ \\ 15 = \frac{Profit \times 100}{12000} \\ \\ Profit = \frac{12000 \times15}{100} \\ \\ Profit= 1800$

SP = CP + profit

SP = 12000+1800

SP=13800

--------------------------------------------------

METHOD 2

Directly use the formula

$SP = CP \times \frac{100 + Profit\%}{100} \\ \\ SP = 12000 \times \frac{100 + 15}{100} \\ \\ SP = 120 \times 115 \\ \\ SP = 13800$
