Question

Out of 20 creepy-crawly creatures in a room, 80% are flies and 20% are spiders.

If S% of the total legs belong to spiders, what is S?

Answer 1

I Believe that S=25%

Answer 2

Answer: S=25

Explanation:

Given: Total creepy-crawly creatures in a room=20

Also, there are 20 % are spiders.

Since 20%=0.2

The number of spiders=
`0.2*20=4`

Then number of flies= 20-4=16

Since flies has 6 legs, then the number of legs in all flies=
`6*16=96`

Also, spider has 8 legs, then the number of all legs in spiders=
`8*4=32`

Total legs of all creepy crawls= 96+32=128

The percent of spider legs=
`(32)/(128)*100=25\%`

hence, if S% of the total legs belong to spiders, then S=25
