Answer 2

Answer:

20%

Step-by-step explanation:

Original price of chair = 2100

New price = 2520

Increase in price = 2520-2100= 420

So, percentage of increase = $\frac{\text{Increase in price}}{\text{original price}} \times 100$

                                              = $\frac{420}{2100} \times 100$

                                              = $20\%$

Hence the percentage of increase is 20%
