Before moving to shortcuts, consolidate these into memory — every question in this chapter reduces to one or a combination of these lines:

Concept	Formula
Profit	SP − CP
Loss	CP − SP
Profit%	(Profit/CP) × 100
Loss%	(Loss/CP) × 100
SP given profit%	CP × (100+p)/100
SP given loss%	CP × (100−l)/100
CP given profit%	SP × 100/(100+p)
CP given loss%	SP × 100/(100−l)
Discount	MP − SP
Discount%	(Discount/MP) × 100
SP given discount%	MP × (100−d)/100
MP given discount%	SP × 100/(100−d)
Two successive discounts	a + b − ab/100
Two successive markups	a + b + ab/100
Markup r% then discount r%	Net loss = r²/100 %
False weight (w in place of 1000g, sold at CP)	Profit% = [(1000−w)/w] × 100
Same SP, x% profit & x% loss	Net loss = x²/100 %
Partnership profit ratio	(Capital × Time) of each partner
