let CP be x
if profit is 300% then SP= CP+3CP
SP=4CP
let the new CP be
=CP + CP*25/100
=1.25 CP
the SP remains the same, that is 4CP
Therefore the profit %= SP - CP / CP *100
= 4CP - 1.25 CP / 1.25 CP *100
=2.75*100/1.25
= 220%
if profit is 300% then SP= CP+3CP
SP=4CP
let the new CP be
=CP + CP*25/100
=1.25 CP
the SP remains the same, that is 4CP
Therefore the profit %= SP - CP / CP *100
= 4CP - 1.25 CP / 1.25 CP *100
=2.75*100/1.25
= 220%
