Question

There are 4 times as many alligators as crocodiles. If the total number of alligators and crocodiles is 40 , how many alligators are there

Answer 1

You need to put them in groups of 5 ( 4 alligators+1 crocodile)
40/5=8 groups
32 alligators, 8 crocodile

Answer 2

There are 8 crocodiles and 32 alligators.

Solution-

Let's assume,

number of crocodiles = x, so number of alligators = 4x

As the total number of alligators and crocodiles is 40, so

`\Rightarrow x+4x=40`

`\Rightarrow 5x=40`

`\Rightarrow x=(40)/(5)`

`\Rightarrow x=8`

`\Rightarrow 4* x=4* 8`

`\Rightarrow 4x=32`

So, there are 8 crocodiles and 32 alligators.
