When twins were born the estate was properly divided thus:—
| Taking the daughter’s share as | 1 | |
| The widow’s share would be | 2 | |
| And the son’s share | 4 | |
| Total | 7 | shares. |
So the son takes four-sevenths, the widow two-sevenths, and the daughter one-seventh of the estate.

If each of my strides forwards or backwards across a 22 feet carpet is 2 feet, and I make a stride every second; and if I take three strides forwards and two backwards until I cross the carpet, I reach the end of it in forty-three seconds. In three steps I advance 6 feet. Then in two steps I retrace 4 feet, thus gaining only 2 feet in five steps, i.e., in five seconds. I therefore advance 16 feet in forty seconds, and three more strides cover the remaining 6 feet.
