The data here shows an hypothetical age distribution of the population of a town in Nigeria.
| Sex | Age in years | |||
| 10 and below | 11-14 15-3 | 36 - 64 | 65 and above | |
| Male | 1350 | 2275 1135 | Y | 3250 |
| Female | 2650 | 2725 1365 | 4265 | Z |
| Total | 4000 | X 2500 | 7500 | 6000 |
From this data, calculate:
(a) X, Y, Z.
(b) The total population of the town.
(c) The difference be-tween 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.
Use the table to answer the following questions:
| Quantity of yams(kg) | Total Revenue (TR) | Marginal Revenue (MR) | Total Cost (TC) | Marginal Cost (MC) |
| N | N | N | N | |
| 0 | 0 | - | 5 | - |
| 1 | 9 | 9 | 8 | 3 |
| 2 | 18 | 9 | 6 | T |
| 3 | 24 | 6 | 21 | 5 |
| 4 | 28 | Q | 25 | 4 |
| 5 | 30 | 2 | 25 | U |
| 6 | P | 1 | 25 | 0 |
| 7 | 28 | -3 | S | 1 |
| 8 | 24 | R | 24 | -2 |
(a) Complete the table by calculating the missing figures P,Q,R,S,T,U.
(b)At what out-put is profit maximized?
(c) Calculate the profit when quantity sold is 5.
(d) At what output does MC begin to rise?
