Let the Marked price be 100 
so after discount of 30 % , SP= 100−30% of 100 
=100−30/100*100
= 70

=>  now profit = 30 % so let CP is x so

x+30% of x = 70
 x+30x/100= 70 

130x/100= 70 so x = 700/13


700/13 now if the discount is 40% the SP
= 100−40% of 100 = 100−40/100×100= 60

So, CP= 700/13 and SP = 60 

$so \: here \: profit \: \: = \frac{60 - \frac{700}{13} }{ \frac{700}{13} } \times 100 = \frac{780 - 700}{700} \times 100 \\ \\ = \frac{80}{7} = 11.42 \: \: \% \: profit$
