From the above data calculate: (a) X, Y, Z (b) The total population of the town (c) the difference between the population of male and female aged 14 and below (d) The percentage of the population aged 14 and below (e) the dependency ratio in the town.

X represents the total population for the age group 11-14.

$$X = \text{Male (11-14)} + \text{Female (11-14)}$$ $$X = 2275 + 2725$$ $$X = 5000$$

Y represents the male population for the age group 36-64. The total for this group is 7500, and the female population is 4265.

$$Y = \text{Total (36-64)} - \text{Female (36-64)}$$ $$Y = 7500 - 4265$$ $$Y = 3235$$

Z represents the female population for the age group 65 and above. The male population is 3250, and the total for this group is 6000.

$$Z = \text{Total (65 and above)} - \text{Male (65 and above)}$$ $$Z = 6000 - 3250$$ $$Z = 2750$$

The values are: $\boxed{X = 5000, Y = 3235, Z = 2750}$

The total populations for each age group are:
10 and below: 4000
11-14: X = 5000
15-35: 2500
36-64: 7500
65 and above: 6000

$$\text{Total Population} = 4000 + 5000 + 2500 + 7500 + 6000$$ $$\text{Total Population} = 25000$$

The total population of the town is $\boxed{25000}$.

$$\text{Male (14 and below)} = \text{Male (10 and below)} + \text{Male (11-14)}$$ $$\text{Male (14 and below)} = 1350 + 2275$$ $$\text{Male (14 and below)} = 3625$$

$$\text{Female (14 and below)} = \text{Female (10 and below)} + \text{Female (11-14)}$$ $$\text{Female (14 and below)} = 2650 + 2725$$ $$\text{Female (14 and below)} = 5375$$

$$\text{Difference} = |\text{Male (14 and below)} - \text{Female (14 and below)}|$$ $$\text{Difference} = |3625 - 5375|$$ $$\text{Difference} = |-1750|$$ $$\text{Difference} = 1750$$

The difference is $\boxed{1750}$.

$$\text{Population (14 and below)} = \text{Total (10 and below)} + \text{Total (11-14)}$$ $$\text{Population (14 and below)} = 4000 + 5000$$ $$\text{Population (14 and below)} = 9000$$

$$\text{Percentage} = \frac{\text{Population (14 and below)}}{\text{Total Population}} \times 100\%$$ $$\text{Percentage} = \frac{9000}{25000} \times 100\%$$ $$\text{Percentage} = \frac{9}{25} \times 100\%$$ $$\text{Percentage} = 0.36 \times 100\%$$ $$\text{Percentage} = 36\%$$

The percentage of the population aged 14 and below is $\boxed{36\%}$.

The dependent population includes those aged 0-14 and 65 and above.

$$\text{Youth Dependent Population (0-14)} = \text{Population (14 and below)} = 9000$$ $$\text{Elderly Dependent Population (65+)} = \text{Total (65 and above)} = 6000$$ $$\text{Total Dependent Population} = 9000 + 6000 = 15000$$

The working-age population includes those aged 15-64.

$$\text{Working Age Population (15-64)} = \text{Total (15-35)} + \text{Total (36-64)}$$ $$\text{Working Age Population (15-64)} = 2500 + 7500$$ $$\text{Working Age Population (15-64)} = 10000$$

$$\text{Dependency Ratio} = \frac{\text{Total Dependent Population}}{\text{Working Age Population}} \times 100$$ $$\text{Dependency Ratio} = \frac{15000}{10000} \times 100$$ $$\text{Dependency Ratio} = 1.5 \times 100$$ $$\text{Dependency Ratio} = 150$$

The dependency ratio in the town is $\boxed{150}$.
