Question: In the fall, a tree drops a tenth of its initial quantity of leaves each day over the course of four days, then abruptly drops the rest on the fifth day. If it had 340 leaves before they started to fall, how many leaves does it drop on the fifth day?
Answer: The tree drops 340 / 10 = 34 leaves for each of the four days. Thus, it drops 34 * 4 = 136 leaves over the first four days. Therefore, it drops 340 - 136 = 204 leaves on the fifth day. The answer is 204.

Norma left 9 T - shirts And twice as many sweaters, she took 9 * 2 = 18 sweaters. Adding the T - shirts and sweaters, Norma left 9 + 18 = 27 clothes. When she came back, she found 3 sweaters And triple the number of T - shirts, she found 3 * 3 = 9 T - shirts. Adding the T - shirts and sweaters, Norma found 3 + 9 = 12 clothes. Subtracting the clothes she left from the clothes she found, 27 - 12 = 15 clothes are missing. The answer is 15.
