Answer: 25
Step-by-step explanation:
Since, Total creepy-crawly creatures = 20
Out of which 80% are flies and 20% are spiders,
Thus, the total flies = 80% of 20 = 16
And, The total spiders = 20% of 20 = 4
Also, we know that the number of legs of a spider = 8,
⇒ Total legs belong to spiders out of 20 creepy-crawly creatures = 4×8 = 32
Again, the number of legs of a fly = 6
Thus, the total legs belong to flies out of 20 creepy-crawly creatures = 6×16 = 96
Hence, Total legs = 32 + 96 = 128
