Mathematical rotation
When the first wheel turns three times, the second wheel turns seven times.

Party A transfers 54 times, and Party B transfers 7/3*54= 126 times.

B turns 9 times, and C only needs to turn 2 times.

When the second wheel 126 turns, the third wheel 126/9*2=28 turns.

Wheel c needs to turn 28 times.

The fifth power in 2009-the seventh power in 2008+65438+the fifth power in 2007.

Power of 2007 = 5 * 5 * 5-Power of 2007 = 7 * 5 * 5+ 10 * 5.

=(25-35+ 10)*5 to the 2007 power.

I finished 22% of the whole journey on the first day and 23% of the whole journey on the second day.

Remaining 1-22%-23%=55%

The distance ratio of repairs in the last three days is 4: 4: 3.

Then the proportion of all courses completed on the last day is 3/(4+4+3)*55%= 15%.

Set the road length x

15%x=27

x= 180

This highway is180m long.

Let's take x grams of water from container A and container B respectively.

[5% *(800-x)+ 10% x]/800 =[ 10% *(200-x)+5% x]/200

x= 160

Take out160g of water from container A and container B respectively.
