I don't know what the nationwide "average" is for an 8 year old boy, but my 8 year old son has always been in the 50th percentile on the doctors growth chart for weight and height which is considered "average" and he is 53 lbs and 49" tall.
The number of calories a 49 year old woman needs a day depends upon her weight but the average would be around 2,000 calories a day.
For women: Ideal Body Weight (in kilograms) = 49 kg + 1.7 kg for each inch over 5 feet. This for adult women.
49
The average is 35. (21 + 35 + 49 (=105), divided by 3.)
