Reasoning and answer: The total number of panels required is 20 * 10 = 200 panels. When 50 failed to be delivered, the total number available for use became 200 - 50 = 150 panels. If each home requires 10 panels, the number of homes that had panels installed is 150 / 10 = 15 homes.
The answer: 15

Question: Faith's neighborhood, with a total of 20 homes, decided to install solar panels. Each home needed 10 panels capable of providing their power needs.

In a week, each section collected 280 / 2 = 140 kilos of newspapers. So, in three weeks, one section collected 140 x 3 = 420 kilos. So, the four sections collected a total of 420 x 4 = 1680 kilos. Hence, their target is to collect 1680 + 320 = 2000 kilos of the newspaper.
The answer: 2000
Reverse engineering the question: Six Grade 4 sections launched a recycling drive where they collect old newspapers to recycle. Each section collected 280 kilos in two weeks. After the third week, they found that they need 320 kilos more to reach their target. How many kilos of the newspaper is their target?


Reasoning and answer: People that do not have glasses 100% - 40% = 60%. 325(.10) = 32.5. 32.5 * 6 = 195 students.

Reasoning and answer: The school band earned $10 / family * 3 families = $30 from three families. The school band earned $15 / family * 5 families = $75 from 15 families. The school band earned $30 + $75 = $105 total. The school band needs $150 - $105 = $45 more to reach their goal.
The answer: 45
What was the question?
Question: The school band is having a car wash to raise money. Their goal is to collect $150. So far they have earned $10 each from three families and $5 each from 15 families. How much more money do they have to earn to reach their goal?


Reasoning and answer: If the sum of their ages is 140, and Asaf is 50 years old, Alexander is 140 - 50 = 90 years old. The age difference between Asaf and Alexander's age is 90 - 50 = 40. Since the age difference between Asaf and Alexander's age is half the total number of pencils Asaf has, Asaf has 2 * 40 = 80 pencils. If Alexander has 60 more pencils than Asaf, Alexander has 80 + 60 = 140 pencils. Together, they have 140 + 80 = 220 pencils.
The answer: 220
What was the question?
Question:
The age difference between Asaf and Alexander's age is half the total number of pencils Asaf has. The sum of their ages is 140, and Asaf is 50 years old. If Alexander has 60 more pencils than Asaf, calculate the total number of pencils they have together.
