Question

by selling a TV for rupees 8000 supervisors loses 20% of his cost if he sells it for RS 11,000 what profit or loss would be there for him

Answer 1

1400 rupee profit cuz

20% of 8000 = 1600
Initiial price = 1600 + 8000= 9600
Final rate = 11000
So profit = 11000 - 9600= 1400

Answer 2

$\huge\bold\green{H}\pink{e}\blue{y}$

sp of TV=₹8000

loss%=20%

$sp = cp( \frac{100 - loss\%}{100})$

$sp = cp( \frac{100 - 20}{100} )$

$8000 = cp( \frac{80}{100} \\ \\ 8000 = cp( \frac{4}{5} )$

$8000 \times \frac{5}{4} = cp$

$2000 \times 5 = cp$

$= > 10000 = cp$

$sp2 \: of \: tv \: = 11000$

$profit = sp2 - cp$

$= > 11000 - 10000 = 1000$

hope this helps you
