For a ten year old boy, I think they should weigh 75 to 80 pounds.
It depends more on their height than their age. Their body mass index (BMI) can be a reasonable measure of whether they are at a suitable weight. It can be calculated by dividing their weight in kilogrammes by their height in metres squared, and comparing the answer to values given on a chart. (There are charts available for free from many websites with a quick search, E.g. one is available on the wikipedia page for BMI http://en.wikipedia.org/wiki/Body_mass_index)
So if for example the 10 year old was 1.2 metres tall and weighed 40 kilogrammes, their BMI would be:
1.2 x 1.2 = 1.44
40 ÷ 1.44 = 27.78 (Overweight according to the chart)
Bear in mind that the chart isn't always completely reliable, for example a very muscular person may be classified as overweight due to the weight for their height.
