Question

give me all the formulas related to percentage (gain ,loss ,c.p,'s. p)

Answer 1

Profit=SP- CP
Loss=CP-SP
Profit%=Profit/CP×100=SP-CP/CP×100
Loss%=Loss/CP×100=CP-SP/CP×100
CP=100×SP/100+r if there is loss of r%
SP=100-r/100×CP
CP=100×SP/100-r if there is profit of r%
SP=100+r/100×CP
When there are 2 successive profit of u%and v% then profit% =u+v+uv/100
When there is profit of u%and loss of v% then profit or loss % = u-v-uv/100
