Answer 2

Profit = 5%

S.P = 8400

C.P =

$\frac{sp \times 100}{100 + p\%}$

$= \frac{8400 \times 100}{5 + 100}$

$= \frac{840000}{105}$

$= \frac{840000}{105} = 8000$

therefore cp = 8000

Checking

➜S.P = 8400

➜C.P = 8000

➜Profit = ?

➝Profit = S.P - C.P

➝Profit = 400

➝Profit % = Profit × 100/C.P

➝Profit % = 400 × 100/8000

➝Profit % = 40/8 = 5%
