Answer this question:My mother celebrated her birthday with a total of 60 guests. Half of the guests are women, 15 are men, and the rest are children. In the middle of the celebration, 1/3 of the men and 5 children left. How many people stayed and enjoyed the birthday celebration?
There were 60 guests / 2 = 30 women at my mother's birthday celebration. There were 30 women + 15 men = 45 men and women. So, 60 people - 45 men and women = 15 were children. Then, 15 men / 3 = 5 men left. Thus, 5 men + 5 children = 10 people left. Therefore, 60 people - 10 people = 50 people stayed and enjoyed the birthday celebration.
The answer is 50.

Answer this question:It is raining outside and Bill puts his empty fish tank in his yard to let it fill with rainwater. It starts raining at 1 pm. 2 inches of rainfall in the first hour. For the next four hours, it rains at a rate of 1 inch per hour. It then rains at three inches per hour for the rest of the day. If the fish tank is 18 inches tall, at what time will it be filled with rainwater.
At 2 pm there are 2 inches of rain in the tank. At 6pm, there are 2 + 4 * 1 = 6 inches of rain in the tank. That means that there are 18 - 6 = 12 inches of tank that still need to be filled as of 6 pm. It will take 12 / 3 = 4 hours to finish filling the tank. The tank will be filled at 6 + 4 = 10pm.
The answer is 10.

When he closed 1 / 4 of the tabs, he closed 1 / 4 * 400 = 100 tabs. The number of windows tabs that remained open is 400 - 100 = 300. After reading some news from different pages, he closed 2 / 5 of the remaining tabs, a total of 2 / 5 * 300 = 120 pages. The number of tabs that remained open is 300 - 120 = 180. If he closed half of the remaining tabs after further analyzing some pages, he closed a total of 1 / 2 * 180 = 90 pages. The total number of tabs that remained opened is 180 - 90 = 90.
The answer is 90.
