sp1 = 700
profit = 25%
so cp = (sp × 100)/(100 + profit%)
= ( 700 × 100)/(100+25)
= (700 × 100)/125
= 5.6 × 100
= 560
again,
sp2 = 700
loss = 20%
cp = (sp × 100)/(100 - loss%)
= (700 × 100)/(100-20)
= (700 × 100)/80
= 175 × 5
= 875
total cp = 560 + 875 = 1435
total sp = 700 × 2 = 1400
since sp greater than cp so profit
= 1435 - 1400
= 35
therefore profit % = (profit × 100)/(cp)
= (35 × 100)/1400
= 35/14
= 2.5%
profit = 25%
so cp = (sp × 100)/(100 + profit%)
= ( 700 × 100)/(100+25)
= (700 × 100)/125
= 5.6 × 100
= 560
again,
sp2 = 700
loss = 20%
cp = (sp × 100)/(100 - loss%)
= (700 × 100)/(100-20)
= (700 × 100)/80
= 175 × 5
= 875
total cp = 560 + 875 = 1435
total sp = 700 × 2 = 1400
since sp greater than cp so profit
= 1435 - 1400
= 35
therefore profit % = (profit × 100)/(cp)
= (35 × 100)/1400
= 35/14
= 2.5%
