Interesting math story
Milan acid powder lamp
Milanfen and other sisters met in Zongbofu and went to Xiao 'ao Mountain to see the lights. There are two kinds of lights upstairs, one is the three big balls above and six small balls below, and the other is the 18 ball below the three big balls above. There are two kinds of lights downstairs, one is 1 big ball with two small balls, and the other is 1 big ball with four small balls. It is known that there are 396 large light balls upstairs, 1440 small light balls, 360 large light balls downstairs and 1200 small light balls.
How many kinds of four kinds of lights are there upstairs and downstairs? Students, can you work it out?
answer
Milan Fen said: "In the downstairs theory, the number of small bulbs is halved to get 600, and the number of headlight bulbs is subtracted from 360. The number of lamps decorated with four small bulbs is 240, and the number of lamps decorated with two small bulbs is 360 MINUS 240, which is 120. This uses the method of' chicken and rabbit in the same cage'. " Calculate the number of lights upstairs in the same way: "Fold 1440, and you get 720,720-396 = 324,324 ÷ 6 = 54. 18 The number of lights in the small bulb is 54. Use 396-54×3=234 and 234÷3=78. That is to say, the number of lights in six small balls is 78. "
