There s a math problem, please do me a favor!

Solution: Set these four people to a total of x yuan.

A accounts for 1 3 of the other three

If you think of A as 1, then the other three are 3

So A accounts for 1 (1+3) = 1 4

In the same way, B accounts for 1 5 of the total, and C is 1 6

So, x 4+x 5+x 6+92=x

x-x/4-x/5-x/6=92

1-1/4-1/5-1/6)x=92

23/60)x=92

x=92/(23/60)=240

A: 240 4 = 60 yuan.

B: 240 5 = 48 yuan.

C: 240 6 = 40 yuan.

Let the money be x and list the equation as: x ((1 3) x (1 4) x (1 5)x) 97

Think of your own as 1, others are 3, 4, 5 times, so.

A accounts for 1 4, B 1 5, and C 1 6, so D is 1-1 4-1 5-1 6 = 23 60

The total amount of money is 92 23 60 = 240

A 60, B 48, C 40, D 92

There must be an unknown number, the sum is x, A is 1 3 of other people, which means that A accounts for 1 percent, and others are 3 percent, then A is 1x 4 of the total, and similarly, B accounts for 1 percent, and the other 4 percent, B is 1x 5, C is 1x 5, and the column equation, x 4+x 5+x 6=92=x, and calculates x=240, then A=60 B=48 C=40

Let A have x yuan, B has y yuan, C has z yuan, then x=1 3(y+z+92).

If A's money is one-third of the sum of the other three's money, then the sum of the other three people's money is three times that of A, and A's money is one-quarter of the sum of the money.

If B has a quarter of the money of the other three people combined, then the sum of the other three people is four times that of A, and A has one-fifth of the sum of the money.

If C's money is one-fifth of the sum of the other three's money, then the sum of the other three people's money is five times that of A, and A's money is one-sixth of the sum of the money.

So what about what fraction of Ding's money is the sum of the money? 1-1/4 -1/5 -1/6 =（60-15-12-10）/60=13/60

Ding has 92 yuan, so the sum of the money = 240

A travels 40 kilometers per hour, and the speed ratio of car B to car A is 4:5, then the speed of vehicle B is 40 * (4 5) = 30 kilometers of troublesome hours.

How many hours after the departure of the two cars: 360 (40+32) = 5 hours.
