| Store | Respective ratio of number of linen kurtis to cotton kurtis sold |
| A | 7:5 |
| B | 5:6 |
| C | 3:2 |
| D | 5:3 |
| E | 4:3 |
| F | 7:3 |

The goal is to determine the percentage increase in kurtis sold by store D relative to linen kurtis sold by store B.
Store D sold 12% of 84,000 total kurtis.
\( \text{Total kurtis sold by store D} = 84,000 \times \frac{12}{100} = 10,080 \)\
Store B sold 22% of the total kurtis. The ratio of linen to cotton kurtis for store B is 5 : 6.
\( \text{Total kurtis sold by store B} = 84,000 \times \frac{22}{100} = 18,480 \)\
Calculate linen kurtis sold by store B:
\( \text{Linen kurtis sold by store B} = \frac{5}{11} \times 18,480 = 8,400 \)\
The percentage increase formula is:
\( \text{Percentage increase} = \frac{\text{Difference}}{\text{Original value}} \times 100. \)\
The difference is:
\( \text{Difference} = 10,080 - 8,400 = 1,680. \)\
Calculate percentage increase:
\( \text{Percentage increase} = \frac{1,680}{8,400} \times 100 = 20\%. \)\
Therefore, kurtis sold by store D is 20% more than linen kurtis sold by store B.
