Answer 1

To find the number of garden men, you can set up an equation using the given information and solve for x. By simplifying the equation, you find that there are 5 garden men in total.

Step-by-step explanation:

To find the number of garden men, we can set up an equation using the given information. Let's say the number of garden men is 'x'.

Total cost of house girls = 3 * 4000 = 12000

Total cost of watchmen = 2 * 5000 = 10000

Total cost of garden men = x * 7000

Given that the average monthly payment is 5700, we can set up the equation:

(12000 + 10000 + x * 7000) / (3 + 2 + x) = 5700

Simplifying the equation:

22000 + 7000x = 5 * 5700 + 5700x

22000 + 7000x = 28500 + 5700x

1300x = 6500

x = 5

Therefore, there are 5 garden men in total.
