Can you help him find the number of men, dogs and spiders in the group?

### Hint

Men have 2 legs,Dogs have 4 legs and

Spiders have 8 legs.

### Answer

Lester found that there were 10 men, 20 dogs and 40 spiders in the group.If you consider the group to consist of 1 man, 2 dogs and 4 spiders, the number of legs will be 42 (This is the least value possible with the given ratio). Since 420 is ten times 42, you must multiply this ratio of men to dogs to spiders by 10 to get the answer.
