Question: Jairus read 20 pages of the newspaper. Arniel read 2 more than twice the number of pages Jairus read. How many pages have they read altogether?
Answer with step-by-step thinking: Twice the number of pages Jairus read is 20 x 2 = 40. Arniel read 40 + 2 = 42 pages of the newspaper. Jairus and Arniel read 20 + 42 = 62 pages altogether.
So the answer is 62.


Question: Mr. Finnegan has 3 tanks with a capacity of 7000 gallons, 5000 gallons, and 3000 gallons, respectively. If he fills the first tank up to 3/4 full, the second tank with water up to 4/5 of its capacity, and the third tank up to half of its capacity, how many gallons in total are in the tanks?
Answer with step-by-step thinking: The capacity of the first tank is 7000 gallons, and if it is filled up to 3 / 4 full, it carries 3 / 4 * 7000 = 5250 gallons. When the second tank is filled up to 4 / 5 of its capacity, it carries 4 / 5 * 5000 = 4000 gallons. The total amount of water in the first two tanks is 5250 + 4000 = 9250 gallons. If Mr. Finnegan fills the third tank with water up to half its capacity, the tank fills up with 1 / 2 * 3000 = 1500 gallons. In total, the three tanks have 9350 + 1500 = 10850 gallons of water.
So the answer is 10850.

If 10 hens lay 80 eggs, then 1 hen lays 80 / 10 = 8 eggs in 10 days. That means one hen is laying 8 / 2 = 4 eggs in 5 days. So in 15 days, 1 hen will lay 3 times more eggs, so 4 * 3 = 12 eggs. All hens in total will then lay 25 * 12 = 300 eggs in 15 days.
So the answer is 300.
