We have a question: Rohan owns a 20-square meter coconut farm. Each square meter has 2 coconut trees and each tree has 6 coconuts. If the coconuts can be harvested every 3 months and each coconut costs $0.50, how much will he earn after 6 months?
And an answer: 240
So how you got the answer?
Rohan has a total of 20 x 2 = 40 coconut trees. And he has a total of 40 x 6 = 240 coconuts. So, the total coconut he will have after 6 months is 240 x 2 = 480. Therefore, the total amount he will earn is 480 x $0.50 = $240.

We have a question: There were 37 jellybeans in a jar. Pat removed 15 of them. Pat then added 5 of the removed jellybeans back in, and then removed 4 more. How many jellybeans are now in the jar?
And an answer: 23
So how you got the answer?
After removing 15 jellybeans, there were 37 - 15 = 22 jellybeans in the jar. After adding back 5 jellybeans, there were 22 + 5 = 27 jellybeans in the jar. After removing 4 more jellybeans, there were 27 - 4 = 23 jellybeans left in the jar.

We have a question: Kenny wants to make sure he does more jumping jacks every week than he did the week before. He recorded that last week he did 324 total jumping jacks. On Saturday of this week, he looks at his records and sees that on Sunday he did 34. On Monday he did 20. On Tuesday he skipped a day. On Wednesday he did 123. On Thursday he did 64. On Friday he did 23. How many does he have to do on Saturday to make sure he beats last week's number?
And an answer: 61
So how you got the answer?
He has already done 264 this week because 34 + 20 + 123 + 64 + 23 = 264. If he does 60 he will have done as many as last week because 324 - 264 = 60. He has to do 61 on Saturday because 60 + 1 = 61.
