general Stock 213 l. 10 s. I require to know each mans share in the loss.
As 794 l. is to 213 l. 10 s. so is 148 l. 17 s. 6 d. to 40 l. 00 s. 7 d. ½
As 794 l. is to 213 l. 10 s. so is 198 l. 10 s. 0 d. to 53 l. 7 s. 6 d.
As 794 l. is to 213 l. 10 s. so is 446 l. 12 s. 6 d. to 120 l. 1 s. 10 d. ½.
Answer.
| A hath lost | 40 | 00 | 7 ½ |
| B | 53 | 07 | 6 |
| C | 120 | 01 | 10 ½ |
| 213 | 10 |
Here in this Example A hath lost 40 l. 7 d. ½, B hath lost 53: 7: 6, and C hath lost 120: 1: 10: ½; each bearing such a proportional share in the Loss as they have in the general Stock, and their respective shares in the Loss maketh up the just Sum of 213 l. 10 s. the general Loss as before.
