Guess the Boy's age?

+1 vote
673 views

It appears that an Clever teacher being desirous of bringing together a number of older students into a class he was forming, offered to give a prize each day to the side of boys or girls whose combined ages would prove to be the greatest.

Well, on the first day there was only one boy and one girl in attendance, and, as the boy's age was just twice that of the girl's, the first day's prize went to the boy.

The next day the girl brought her sister to school, and it was found that their combined ages were just twice that of the boy, so the two girls divided the prize.

When school opened the next day, however, the boy had recruited one of his brothers, and it was found that the combined ages of the two boys were exactly twice as much as the ages of the two girls, so the boys carried off the honors of that day and divided the prizes between them.

The battle waxed warm and on the fourth day the two girls appeared accompanied by their elder sister; so it was then the combined ages of the three girls against the two boys, and the girls won off course, once more bringing their ages up to just twice that of the boys'. The struggle went on until the class was filled up, but as our problem does not need to go further than this point, to tell the age of that first boy, provided that the last young lady joined the class on her twenty-first birthday. Now, guess the first boy's age.

Fresh and invigorated after completing her algebra homework, Mayra appeared at the living room door. She held a piece of paper covered in scribbled numbers, 'm's, 'd's, and equations.

"Dad!" she announced. "Five years from now you'll be only double my age!"

"Amazing!" Dad almost looked up from the TV, but knew she hadn't finished.

"But five years ago, you were triple my age then!"

"I suppose," Dad grunted, changing channels.

How old is Mayra?
