| 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 objective is to determine the ratio between the total kurtis (linen and cotton) sold by store C and the linen kurtis sold by store F.
Based on the pie chart, store C accounts for 8% of the total kurtis sold, which is 84,000. Thus, the total kurtis sold by C is:
Total kurtis sold by store C = \( 84,000 \times \frac{8}{100} = 6,720 \)
Store F represents 14% of the total kurtis sold. The ratio of linen to cotton kurtis for store F is 7 : 3. This means for every 10 kurtis, 7 are linen.
Total kurtis sold by store F = \( 84,000 \times \frac{14}{100} = 11,760 \)
The number of linen kurtis sold by store F is:
Linen kurtis sold by store F = \( \frac{7}{10} \times 11,760 = 8,232 \)
The required ratio of total kurtis sold by store C to linen kurtis sold by store F is:
Required ratio = \( \frac{\text{Total kurtis sold by store C}}{\text{Linen kurtis sold by store F}} = \frac{6,720}{8,232} \)
Simplifying the ratio:
\( \frac{6,720}{8,232} = \frac{40}{49} \)
