the one who do these all questions correctly I will mark him/her a brainliest and like it so solve them all I will check​

Answer 1

Step-by-step explanation:

Q.1

Profit=SP-CP

4,400-3,800=600

Therefore, Profit=Rs 600

Profit%= Profit/CP × 100

600/3,800 × 100

=15.78%

Therefore Profit%=15.78%

Q.2

Profit%=15%

15/100 × 4,500

=675

SP= Profit+ CP

=675+4,500

=5,175

Therefore Selling price is Rs 5,175

Q.3

Let CP be x

Loss %= 20%

Loss= 20% × x

SP= CP - Loss

8,00,000= x - 20/100× x

8,00,000= (100x-20x)÷100

8,00,00,000=80x

x=8,00,00,000÷80

x=10,00,000

Therefore, CP of the house is Rs 10,00,000

Now mark me as brainliest.
