let CP be 100..
profit = 320 and SP = 100+320=420

If CP increases by 25%, CP becomes = 125
Profit = 420-125 = 295 Nearly 300
Profit as % of Sp = $$\frac{300}{420}*100=\frac{1000}{14}=71%$$
B 70%

Cp =100
Profit = 320% of 100 = 320
So
Sp = cp+profit= 420
Now cp = 100 + 25 = 125
Sp = 420
Now profit = 295
So % of selling price is profit =( 295/420)*100
=~ 70...
