If Darius scored 10 points, then Marius scored 10 + 3 = 13 points in total. Darius scored 5 points less than Matt, so Matt scored 10 + 5 = 15 points in total. So all three friends gathered 13 + 15 + 10 = 38 points.
The answer: 38
Reverse engineering the question: Darius, Matt, and Marius are friends, who played table football. During all the games they played, Marius scored 3 points more than Darius, and Darius scored 5 points less than Matt. How many points did all three friends score together, if Darius scored 10 points?

The number of cows and foxes in the yacht is 20 + 15 = 35. Mr. Bodhi also has three times as many zebras as foxes in the yacht, equal to 3 * 15 = 45 zebras. The number of animals in the yacht so far is 35 + 45 = 80. To balance the yacht, Mr. Bodhi needs to add 100 - 80 = 20 sheep.
The answer: 20
Reverse engineering the question: Mr. Bodhi is transporting some animals using a yacht across a river. He has 20 cows, 15 foxes and three times as many zebras as foxes. To balance the yacht to ensure a smooth sail across the river, the total number of animals in the yacht needs to be 100. If he decides to add sheep to the yacht to make the yacht sail-worthy, how many sheep did he add to the yacht?

At first, there were 7 * 12 = 84 chairs. Later, there were 84 + 11 = 95 chairs altogether.
The answer: 95
Reverse engineering the question: For a wedding, chairs were arranged in 7 rows with 12 chairs in each row. Some people arrived late and grabbed 11 extra chairs, placing them at the back. How many chairs were there altogether?

Robi will save $8 x 2 = $16 in April. He will save $16 x 2 = $32 in May. He will save $32 x 2 = $64 in June. Hence, his total savings after 6 months will be $2 + $4 + $8 + $16 + $32 + $64 = $126.
The answer: 126
Reverse engineering the question:
One of Robi's new year's resolutions is to start saving. He started to save $2 in January. This is followed by $4 in February and $8 in March. If he continues this saving pattern, how much will be his total savings after 6 months?
