Answer:
S.P = 500;  C.P = 400

Question:
What loss will one incur if a product worth Rs. 3000 is sold for Rs. 2400?
Answer:
C.P = 3000
S.P = 2400
Loss = 3000 – 2400
= Rs. 600

Question:
A bike worth Rs. 40000 is sold for Rs. 46000. What is the profit percentage?
Answer:
S.P = 46000
C.P = 40000
Substitute the values in the above equation, we get
P% = [(46000-40000)/40000]x100
= 15% profit

Shortcut 32:

Loss percentage

L\%=\frac{C.P-S.P}{C.P}\times100

A mobile phone worth Rs. 9900 is sold for Rs. 9000. What is the percentage loss?
Answer:
S.P = 9000

L% = [(9900-9000)/9900] x 100
L% = 9.09% loss
