Correct Answer - Option 2 : 38%

Given:

While buying he get 15% profit and while selling 20% profit.

Calculation:

Let be assume profit in first trade is x and second trade y

⇒ Shopkeeper get 15% of profit in his first trade

⇒ Shopkeeper get 20% of profit in the second trade

⇒ Final profit of shopkeeper = [x + y + (xy/100)]% 

⇒ [15 + 20 + (15 × 20)/100] = 38%

∴ The required result will be 38%.
