Q: While reading in bed with his wife Susan, Charlie heard a noise at the door. It was Sarah entering the bedroom with 4 friends. If there were also 8 people in the living room, how many people are in the house?
A: In the bedroom, there are 1 + 1 = 2 people in the house (Charlie and Susan). Sarah and four friends then entered, a total of 4 + 1 = 5 people. Together with Charlie and Susan, there are now 5 + 2 = 7 people in the bedroom. Since there are 8 more people in the living room, the total number of people in the house is 8 + 7 = 15. The answer is 15.

Q: The leak in Jerry's roof drips 3 drops a minute into the pot he put under it. Each drop is 20 ml, and the pot holds 3 liters. How long will it take the pot to be full?
A: First find the pot's volume in ml: 3 liters * 1000 ml / liter = 3000 ml. Then find the number of ml that enter the pot per minute: 3 drops / minute * 20 ml / drop = 60 ml / minute. Then divide the volume of the pot by the volume that enters it every minute: 3000 ml / 60 ml / minute = 50 minutes. The answer is 50.

Q: Lyla, a grocery store owner, bought rice weighing 30 kg less than green beans, which weigh 10 kg more than sugar. While carrying the goods to the store, the bags fell down and 1/3 weight of the rice and 1/5 weight of sugar was lost. If the green beans weighed 60 kgs, then how much did the remaining stock weigh?
A:
If rice weighed 30 kg less than the green beans, then the total rice weight is 60 kg - 30 kg = 30 kg. If the green beans weighed 10 kg more than sugar, then the total sugar weight is 60 kg - 10 kg = 50 kg. When 1 / 3 weight of rice was lost, the weight loss became 1 / 3 * 30 = 10kg. The weight of rice after the loss is 30 kg - 10 kg = 20 kg. When 1 / 5 weight of sugar was lost, the lost weight was 1 / 5 * 50 kg = 10 kg. The weight of sugar after the loss is 50 kg - 10 kg = 40 kg. The total weight for all the items is 40 kg + 20 kg + 60 kg = 120 kg. The answer is 120.
