POW #5:A Cycling Problem
Orville and Wilbur owned a bicycle shop which also sold tricycles.One day,they decided to take an inventory of their stock.They each volunteered to count one item,which would have worked out just fine if one had counted bicycles and the other had counted tricycles.But,Orville and Wilbur were very independent thinkers.Orville counted the number of pedals in the shop and Wilbur counted the number of wheels.
Orville found that they had 144 pedals in the shop,and Wilbur found that they had 186 wheels.All pedals and wheels were actually parts of either bicycles or tricycles.They were just about to start over with their inventory when their friend,Kitty Hawkins,who was a good problem-solver challenged them to figure out the number of bicycles and tricycles from the inventory they had already done.
Can you help the Wright brothers?

one bicycle has 2 pedals and 2 wheels
one tricycle has 2 pedals and 3 wheels
so total bicycles and tricycles are :144/2=72
tryicles count:186-144=42 (脚踏板是成双出现,自行车脚踏板和轮子是一样多,三人车轮子比脚踏板多出一个,所以.)
then
bicycles:30
tricycles:42
best withes!
