Answer Key : (d) -

Let the original price= 100.  As marked price is 15% more than the original price

∴ Marked price=100+15% of 100 =  115. Again the price is increased by 20%

∴ New price=115+20% of 115 = 115+

Now, original price= 100

New price= 138

∴ Profit %=138-100=38%

Alternative Method (I):

Let the original price= 100

100  115 138

⇒ profit %=38%

If the value is increased successively by and then profit % is given by
