Question: Mary and her two friends came up with the idea of collecting marbles each day for their play on weekends. From Monday to Friday, Mary collected twice as many red marbles as Jenny and half the number of blue marbles collected by Anie, who collected 20 more red marbles than Mary and twice the number of blue marbles Jenny collected. If Jenny collected 30 red marbles and 25 blue marbles, what's the total number of blue marbles collected by the friends together?
Answer: If Mary collected twice the number of red marbles collected by Jenny, she got 2 * 30 = 60 red marbles. Anie collected 20 more red marbles than Mary, which is 60 + 20 = 80 red marbles. The total number of red marbles is 60 + 80 + 30 = 170 red marbles. If Anie collected twice the number of blue marbles collected by Jenny, then she got 2 * 25 = 50 blue marbles. Mary collected half the number of blue marbles collected by Anie, thus 1 / 2 * 50 = 25 marbles. The total number of blue marbles collected is 50 + 25 + 25 = 100 blue marbles. The answer is 100.

Question: Ragnar is a woodchopper. He can get 3 blocks of wood for every tree he cuts. If Ragnar chops 2 trees every day, how many blocks of woods does he get after 5 days?
Answer: Ragnar gets 3 x 2 = 6 blocks of wood every day. Therefore, the total number of blocks of woods he gets after 5 days is 6 x 5 = 30. The answer is 30.

Question: John uses 5 liters of fuel per km to travel. How many liters of fuel should John plan to use if he plans to travel on two trips of 30 km and 20 km?
Answer: The first trip will use 30 * 5 = 150 liters of fuel. The second trip will use 20 * 5 = 100 liters of fuel. The total liters of fuel are 150 + 100 = 250 liters. The answer is 250.

Question: Frank and his friends Betty and Bill went to their farm and picked oranges to eat. Betty picked 15 oranges and Bill picked 12 oranges. Frank picked three times the number that Betty and Bill picked combined. Frank then planted 2 seeds from each of his oranges into the ground and waited 20 years for each seed to turn into a beautiful orange tree. If each orange tree contains 5 oranges for Frank's son Philip to pick, how many oranges are there for Philip to pick in total?
Answer:
Together, Betty and Bill picked 15 + 12 = 27 oranges. Frank picked 3 * 27 = 81 oranges. Frank planted 2 * 81 = 162 seeds in total, so there are 162 orange trees 20 years later. Philip can then pick 162 * 5 = 810 oranges. The answer is 810.
