Q: In a glee club, there are two times as many female than male members. How many female members are there if there are 18 members in the club?
A: The club has a female group which has twice as many members as the male group, so there are 2 + 1 = 3 groups in the club. There are 18 members in the club, which means there are 18 / 3 = 6 members per group. Since the number of female members consists of two groups, then there are 6 * 2 = 12 female members in the club. The answer is 12.

Q: The sum of the ages of two friends, Alma and Melina, is twice the total number of points Alma scored in a test. If Melina is three times as old as Alma, and she is 60, calculate Alma's score in the test?
A: If Melina is three times as old as Alma, and she is 60, Alma is 60 / 3 = 20 years old. The sum of their ages is 60 + 20 = 80 years. Since the sum of Alma and Melina's age is twice the total number of points Alma scored in a test, Alma's score in the test was 80 / 2 = 40 points. The answer is 40.

Q: A store received 20 pallets of paper products to stock. Half the pallets were paper towels, a quarter were tissues, and a fifth were paper plates. The rest were paper cups. How many pallets of paper cups did the store receive?
A:
The store received 20 / 2 = 10 pallets of paper towels. They received 20 / 4 = 5 pallets of tissues. They received 20 / 5 = 4 pallets of paper plates. Thus, the store received 20 - 10 - 5 - 4 = 1 pallet of paper cups. The answer is 1.
