A spider has 8 legs. A dragonfly has 6 legs and 2 pairs of wings. A cicada has 6 legs and one pair of wings. Now we have all 3 kinds and a total of 18 insects in a cage. We have a total of 118 legs and 20 pairs of wings.
How many insects do we have of each kind?
There are 5 Spiders, 7 Dragonfly & 6 Cicada
5 Spiders = 40 Legs & 0 pair of wings 7 Dragonfly = 42 Legs & 14 Pairs of wings 6 Cicada = 36 Legs & 6 pairs of wings.
So, Total 18(5+7+6) insects = 118 (40+42+36) Legs & 20 (0+14+6) Pairs of wings.
