Since, 18 SP = 24 CP.
Therefore, SP = 1.33 CP or profit % = 33.33%.
So, if initial CP = ₹ 100, then initially, he is selling the articles at ₹ 133.33.
Now, in new case, 24 SP = 36 CP,
then SP = 1.5 CP or new profit% = 50%.
So, new SP will be ₹ 150.
Therefore, increase in SP will be

150−133.33

133.33

×100
=

16.66

133.33

×100
= 12.5 %
