by : $27$

 * The First-Born's Legacy
 * Mrs. Goodheart gave birth to twins.
 * The clock showed clearly that Tommy was born about an hour later than Freddy.
 * Mr. Goodheart, who died a few months earlier, had made a will leaving $\pounds 8400$,
 * and had taken the precaution to provide for the possibility of there being twins.
 * In such a case the money was to be divided in the following proportions:
 * two-thirds to the widow,
 * one-fifth to the first-born,
 * one-tenth to the other twin,
 * and one-twelfth to his brother.


 * Now, what is the exact amount that should be settled on Freddy?
