Multiply factors: eighty percent times one hundred twenty five percent equals one. So the final value equals the original.
0.8 × 1.25 = 1.00
Profit is sixty on a base of two hundred forty. That is twenty five percent.
((300-240)/240)*100 = 25
Loss is one hundred twenty on eight hundred. That gives fifteen percent.
((800-680)/800)*100 = 15
Selling price equals one hundred twenty percent of cost. So cost is three sixty divided by one point two which is three hundred.
CP = 360 / 1.20 = 300
Selling price equals marked price times eighty percent. So marked price is eight eighty divided by zero point eight which is eleven hundred.
MP = 880 / 0.80 = 1100
Apply successive growth. One thousand times one point one times one point two equals one thousand three hundred twenty.
1000 × 1.10 × 1.20 = 1320
Let marked price be one hundred. Selling price is eighty five. Cost price is eighty. Profit is five on a base of eighty which is six point two five percent.
Profit% = (85-80)/80 × 100 = 6.25
Price factor is zero point eight five times zero point nine equals zero point seven six five. Net discount is one minus zero point seven six five equals zero point two three five or twenty three point five percent.
1 - (0.85×0.90) = 0.235
Compute forty five over sixty equals zero point seven five which is seventy five percent.
(45/60)*100 = 75
Increase is twelve on a base of eighty. Twelve by eighty equals zero point one five, which is fifteen percent.
((92-80)/80)*100 = 15
Keep price as one hundred. After twenty percent off it becomes eighty. Then ten percent off gives seventy two. Net discount is twenty eight on one hundred which is twenty eight percent.
1 - (0.8×0.9) = 0.28
Let cost be one hundred and marked be one hundred forty. Target selling is one hundred twelve. Discount fraction equals (140−112)/140 which is zero point two. So twenty percent.
discount% = (140-112)/140 × 100 = 20
Let cost be one. Desired selling price is one point two five. With twenty percent discount, selling price equals marked price times zero point eight. So marked price is one point two five over zero point eight which is one point five six two five. That is fifty six point two five percent markup.
MP/CP = 1.25 / 0.80 = 1.5625
