## Important Formulas

• Loss% = {(loss * 100)/CP}
• Gain% = {(Gain * 100)/CP}
• Discount% = {(Gain * 100)/CP}
• SP = {(100-L%)×CP}/100
• SP = {(100+G%)×CP}/100
• SP = {(100-D%)×MP}/100
• False weight Formula

%Gain = (error/true value- Error)×100

Error = True weight – False weight

• If G1 and G2 are successive profits then Resultant Profit is given by-
[G1 + G2 + {(G1 G2) / 100}]
• When CP and SP is reduced by ‘X’ (same) amount

CP = {(initial G% + increase in G%)× X}/(increase in G%)

• If x articles CP equals y articles SP

G% = {(x-y)×100}/y

• If G1% is made on first article and L2% is made on 2nd article after selling both articles at the same price then, overall Gain% (+ve sign.) or Loss% (-ve sign.) is given by-

G% or L%= [{100(G1 – L2 ) – 2 G1L2} / {(100+G1)+(100-L2)}]
