[Question]Earl started delivering newspapers on the first floor of a condominium building. He then went up 5 floors then went down 2 floors. He again went up 7 floors and found that he is 9 floors away from the top of the building. How many floors does the building have?
[Answer]Earl was on the 1 + 5 = 6th floor after going up 5 floors. When he went down 2 floors, he was on the 6 - 2 = 4th floor. Since he went up 7 floors, he was then on the 4 + 7 = 11th floor. Since he is 9 floors away from the top of the building, therefore the building has 11 + 9 = 20 floors. The answer is 20.

[Question]3/5 of the mangoes on a mango tree are ripe. If Lindsay eats 60% of the ripe mangoes, calculate the number of ripe mangoes remaining if there were 400 mangoes on the tree to start with.
[Answer]The number of ripe mangoes from the tree is 3 / 5 * 400 = 240. If Lindsay eats 60% of the ripe mangoes, she eats 60 / 100 * 240 = 144 mangoes. The total number of ripe mangoes remaining is 240 - 144 = 96. The answer is 96.

The total earnings for the paper cover version were $0.20 x 32 000 = $6,400. So, the author earned $6,400 x 6 / 100 = $384 from the paper cover version. The total earnings for the hardcover version were $0.40 x 15,000 = $6,000. So, the author earned $6,000 x 12 / 100 = $720 from the hardcover version. Therefore, the author earned a total of $384 + $720 = $1104. The answer is 1104.
