She needs to type an additional 1000 – 200 = 800 words. In one minute she can type 300 words / 30 = 10 words. It will take her 800 / 10 = 80 more minutes to finish typing the report.
The answer: 80
Reverse engineering the question: Abigail has a report due tomorrow which needs to be 1000 words in length. Abigail can type 300 words in half an hour. If she has already written 200 words, how many more minutes will it take her to finish the report?


Reasoning and answer: The husband saves $335 x 4 = $1340 a month. The wife saves $225 x4 = $900 a month. Together, they save $1340 + $900 = $2240 in a month. In 6 months, their total savings is $2240 x 6 = $13440. Half of the couple's savings is 13440 / 2 = $6720. Therefore, each child will receive 6720 / 4 = $1680.
The answer: 1680

Question: A couple opened a savings account. The husband gives $335 every week while the wife gives $225 every week. After 6 months of saving (assume 4 weeks in each month), they decided to divide half of the couple's savings into their four children's savings accounts. How much does each child receive?


First figure out how much money Nigella earned from commission by subtracting her base salary from her total earnings: $8,000 - $3,000 = $5,000. Next, figure out how much all three houses cost by dividing Nigella's commission money by her commission rate: $5,000 ÷ 0.02 = $250,000. Next, express each house's price in terms of A's price: B = 3A, and C = 2A - $110,000. Now we know that A + 3A + 2A - $110,000 = $250,000. We can combine like terms to find that 6A - $110,000 = $250,000. Now we add $110,000 to both sides of the equation and get 6A = $360,000. We can divide both sides by 6 to find A = $60,000.
The answer: 60000
Reverse engineering the question: Nigella is a realtor who earns a base salary of $3,000 a month plus a 2% commission on every house she sells. One month, Nigella sells 3 houses and earns $8,000 total. House B costs three times as much as House A. House C cost twice as much as House A minus $110,000. How much did House A cost?


Reasoning and answer: Each table needs 1 plank of wood * 4 legs = 4 planks of wood for the legs. This means each table needs 4 planks of wood for legs + 5 planks of wood for the surface = 9 planks of wood. To build 5 tables, Johnny will therefore need 9 planks of wood * 5 tables = 45 planks of wood.
The answer: 45
What was the question?
Question: Johnny is buying planks of wood to build some tables. Each table needs a plank of wood for each of the legs and 5 planks of wood for the surface. If Johnny wants to build 5 tables, how many planks of wood does he need?


The first group is a third of the class which is (1 / 3) * 45 = 15 students. There are 15 students in the first group, so there are 45 - 15 = 30 students. The second group is two - fifths of the class which is (2 / 5) * 45 = 18 students. There are 18 in the second group so there are 30 - 18 = 12 students left in the third group.
The answer: 12
Reverse engineering the question: Musa is the class teacher of a class of 45 students. He wants to split them into three groups by age. If a third of the class is under 11 years, and two-fifths are above 11 but under 13, how many students will be in the third group (13 years and above)?


George has 3 small pizzas * 4 slices = 12 pieces. George also has 2 large pizzas * 8 slices = 16 slices. Total, George has 12 + 16 slices = 28 slices of pizza. Bob will eat 3 slices + 1 = 4 slices. Susie will eat 1 / 2 * 4 slices = 2 slices. Bob, Fred and Mark will eat in total 3 + 3 + 3 = 9 pieces. Total slices of pizza eaten will be 3 + 4 + 2 + 9 = 18 pieces. Total pizza slices remaining will be 28 pieces - 18 = 10 slices left.
The answer: 10

A small pizza can gives 4 slices, and a large pizza gives 8 slices. George purchased 3 small and 2 large pizzas. George would like to eat 3 pieces. His friend Bob would like to eat one more piece than George. Susie will eat half as many as Bob. Bill, Fred and Mark would each like 3 pieces. How many slices of pizza will be left over?
