It starts raining at 7:00 and pours heavily until its stops at 17:00 on a particular day. On the second day, the rain takes 2 more hours than it took on the first day to stop. On the third day, the rain pours for twice the amount of time it took on the second day. Calculate the total time it was raining in the three days.
Let's think: On the first day, it rained for 17:00 - 7:00 = 10 hours. On the second day, it 10 hours + 2 hours = 12 hours for the rain to stop. It rained for 2 * 12 hours = 24 hours on the third day. In the three days, it was raining for 24 hours + 12 hours + 10 hours = 46 hours.. The answer is: 46.

Tom is cutting a piece of wood to make a shelf. He cut the wood to 143 cm, but it is too long to fit in the bookshelf he is making. He decides to cut 25 cm off the board. But it turned out longer than the other boards. He had to cut off 7 cm from each to make them the same size. How long were the boards before he cut the 7 cm off?
Let's think: After the first cut, the board was 143 - 25 = 118 cm. The other boards were 118 + 7 = 125 cm before they got cut.. The answer is: 125.

Wendy spent 25 years as an accountant and 15 years as an accounting manager. If Wendy lived to be 80 years old, what percentage of her life did she spend in an accounting-related job?
Let's think: First find the total number of years Wendy spent in accounting: 25 years + 15 years = 40 years. Then divide the number of years she spent in accounting by the number of years she lived and multiply by 100% to find the percentage of her life: 40 years / 80 years * 100% = 50%.. The answer is: 50.

Sheila, Purity, and Rose want to rent a house. Sheila has offered to pay five times Purity’s share of the rent. Rose can only afford thrice what Purity pays. If Rose’s share is $1,800, what is the total house rent?
Let's think:
Purity will pay a third of Rose's share, which translates to 1800 / 3 = 600 dollars. Sheila has offered to pay 5 * 600 = 3000 dollars. Combining everyone’s share of the rent will give a total of 600 + 3000 + 1800 = 5400 dollars.. The answer is: 5400.
