Mr. and Mrs. Smith were walking home from the shopping mall with their purchases when Mr. Smith began to complain that his load was too heavy. Mrs. Smith turned to her husband and said, "I don't know what you're complaining about because if you gave me one of your parcels, I would have twice as many as you and if I gave you just one of mine, we would have equal loads." How many parcels was each carrying?
Mrs. Smith was carrying seven parcels and Mr. Smith was carrying five.
In a contest, four fruits (an apple, a banana, an orange, and a pear) have been placed in four closed boxes (one fruit per box). People may guess which fruit is in which box. 123 people participate in the contest. When the boxes are opened, it turns out that 43 people have guessed none of the fruits correctly, 39 people have guessed one fruit correctly, and 31 people have guessed two fruits correctly.
The Question: How many people have guessed three fruits correctly, and how many people have guessed four fruits correctly?
It is not possible to guess only three fruits correctly: the fourth fruit is then correct too! So nobody has guessed three fruits correctly and 123-43-39-31 = 10 people have guessed four fruits correctly.
A large truck is crossing a bridge 1 mile long. The bridge can only hold 14000 lbs, which is the exact weight of the truck. The truck makes it half way across the bridge and stops. A bird lands on the truck. Does the bridge collapse?
No, it does not collapse. Because it has driven a half mile - you would subtract the gas used from the total weight of the truck.
