Question: Job is a farmer who rears cattle and grows crops. In total he has 150 hectares of land. 25 hectares are occupied by his house and farm machinery, and 15 hectares have been reserved for future expansion. 40 hectares are dedicated to rearing cattle. Assuming the rest of his land is used for crops, how many hectares of land does Job use for crop production?
Answer: Job uses 25 + 15 + 40 = 80 hectares of land for non - crop purposes. Thus he uses 150 - 80 = 70 hectares for crop production. The answer is 70.
[Question]John gets lost on his way home. His normal trip is 150 miles and would take him 3 hours. He ends up driving 50 miles out of the way and has to get back on track. How long did the trip take if he kept the same speed?
[Answer]His speed is 150 / 3 = 50 mph. He was detoured 50 * 2 = 100 miles. So that adds 100 / 50 = 2 hours. So the total trip was 3 + 2 = 5 hours. The answer is 5.
Q: Taro and Vlad play a video game competition together, earning 5 points for every win. After playing 30 rounds, Taro scored 4 points less than 3/5 of the total points scored. How many total points did Vlad score?
A: If they played 30 rounds, the total possible points from wins are 5 * 30 = 150 points. Scoring 3 / 5 of the total possible points earns you 3 / 5 * 150 points = 90 points. If Taro scored 4 points less than 3 / 5 of the total points, he scored 90 points - 4 points = 86 points. If the total points scored in the game is 150, then Vlad scored 150 points - 86 points = 64 points. The answer is 64.

His client has him spend four hours on customer outreach posts and half that time on advertisement posts each day. Bryan works eight hours a day.
