|---|---|---|---|---|---|---|
| S1 (both companies X and Y, in %) | 19 | 21 | 15 | 33 | 12 | 6400 |
| S2 (only company X, in %) | 24 | 18 | 20 | 30 | 8 | 3000 |

- D56
Explanation
Company Y sold by showroom E = total sold by E minus company X sold by E = 12% of 6400 - 8% of 3000 = 768 - 240 = 528. Both companies sold by C = 15% of 6400 = 960. Required percentage = 528/960 x 100 = 55%.
