Problem 1:

Spiders have 8 legs.
How many legs do 5 Arachnotrons 
have in total?

A: 20		C: 40
B: 30

Solution: 

Spiders indeed have 8 legs, but Arachnotrons are not spiders
and have only 4 legs. So 5 Arachnotrons would have 5*4 = 20 legs.



Problem 2:

A Cacodemon weighs 50 kg.
How much would it weigh if its diameter
were 2 times larger?

A: 100 kg	C: 400 kg
B: 200 kg

Solution:

When an object is scaled up, its mass increases by the cube of the multiplier.
So our Caco would weigh 50*8 = 400 kg.



Problem 3:

A Mancubus and an Imp ate 12 skulls together.
The fat fuck Mancubus ate 10 more than the Imp.
How many skulls did the Imp eat?

A: 0		C: 2
B: 1

Solution:

Let x be the number of skulls eaten by the Imp.
Then the Manc ate x+10 skulls.
From the simple equation 2x+10 = 12 we get x = 1.



Problem 4:

If 5 Pain Elementals produce 50 Lost Souls 
in 5 minutes, how many Lost Souls will 10
Pain Elementals produce in 10 minutes?

A: 50		C: 200		
B: 100	

Solution:

We had 5 PEs and 5 minutes, and now we have twice as many PEs and twice as much time.
The answer is 50*2*2 = 200.
