Loss percent Shortcut tricks
Formula: Loss% = (Loss x 100/C.P)

Example 1:
A man purchased a toy for Rs. 120 and sold it for Rs. 90, Find the loss Percent.
Answer :
C.P = 120 and S.P =90
So We Know the formula of Loss = C. P – S.P . Loss = (120 – 90) = 30
Loss% = 30 x 100/120 = 25%
So, the loss Percent is 25%.


Example 2:
Anish purchased a mobile for Rs. 12000 and sold it for Rs. 8000, Find the loss Percent.
Answer :
C.P = 12000 and S.P =8000
So We Know the formula of Loss = C. P – S.P, Loss = (12000 – 8000) = 4000
%Loss = 4000 x 100/12000 = 33.33%
So, the loss Percent is 33.33%


Example 3:
10% loss on selling price is what percent loss on the cost price ?
Answer :
consider selling price be = Rs.100, Then loss = Rs.10
Cost price = Rs.( 100 + 10 ) = 110

Example 4 :
A farmer purchased a cow for Rs. 200 and sold it for Rs. 180, Find the loss Percent.
Answer :
C.P = 200 and S.P =180
So We Know the formula of Loss = C.P – S.P . Loss = (200 – 180) =20
%Loss = 20 x 100 / 200 = 10%.
So, the loss Percent is 10%.
