If one and a half boys, eat one and a half burgers in one and a half hours.
How many burgers can 9 boys eat in 3 hours ?
18
More hours => more burgers.
More boys => more burgers.
The time become twice (3 hours / 1.5 hours).
Boys become six times (9 / 1.5).
Number of burgers = 2 * 6 * Original(1.5)
= 18
While anikam’s answer is mathematically correct, he failed to take into account that after one and a half burgers, the boys were full and ate no more in the next one and a half hours. Thus, the answer for nine boys is six.
Noticed a typing error as soon as I hit send. Corrected answer appears below:
