Gotcha.
Here are some simple ones that I did yesterday with times. I got the problems from here in Eternity’s tutoring thread. I haven’t checked the answers yet, and there’s one more I need to do when I’ve got time. I haven’t done another rate one yet but I’ll find some more asap.
- A girl is half as old as her sister and is also two years younger than her brother. If the sum of the three children’s ages is 34 years, what is the product of their ages?
- In a certain school, 2/3 of the faculty are women, 1/4 of the men on the faculty are married and the other 9 men are bachelors. How many faculty members are there?
- John divided his souvenir hat pins into two piles. The two piles had an equal number of pins. He gave his brother one-half of one-third of one pile. John had 66 pins left. How many pins did John originally have?
- If 20 is added to one-third of a number, the result is the double of the number. What is the number?
