Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 26%.

Let the original number = 100 

Step 1: Increase by 5% = 100 + 5% of 100 = 100 + 5 = 105

Step 2: Increase 105 by 20% = 105 + 20% of 105 = 105 + 21 = 126 

So, the final value = 126 

Net Increase = 126 - 100 = 26 

⇒ Net % Increase  =26100×100=26% = \frac{26}{100} \times 100 = {26\%}
