[Question]Yeon has three times as many watermelon seeds as Gwi. Gwi has 40 more watermelon seeds than Bom. If Bom has 300 watermelon seeds, how many seeds do they have together?
[Answer]If Bom has 300 seeds, then Gwi has 300 + 40 = 340 watermelon seeds. Together, Bom and Gwi have 340 + 300 = 640 melon seeds. Yeon's number of watermelon seeds is three times as many as the number that Gwi has, meaning Yeon has 3 * 340 = 1020 watermelon seeds. Together, the three friends have 1020 + 640 = 1660 watermelon seeds. The answer is 1660.

[Question]It takes 3 men an hour to complete a job. If they are hired to work on 5 such similar jobs by a company that pays each of them $10 per hour, calculate the total amount of money the three will earn when they complete the jobs?
[Answer]
Since they are paid $10 each per hour of work and can complete a job in one hour, they earn a total of $10 * 3 = $30 together for an hour of work. If they earn together $30 for one job, for the five jobs, they'll earn $30 * 5 = $150. The answer is 150.
