A little  difficult, TB....!!!!

Let   a  be the amount  pumped   from  tank  B   into C

And since they all  hold the  same amount

Amount in B =  Amount in A

(150 + n)  -  a =   n -  500

150 - a  =  -500     add 500, A  to both sides

a = 650

And the  amount in  C =   amount in A

500 + 650 =  n - 500      add 500  to  both sides

1000 + 650 =   n

1650 = n

Proof

A  contains  1650  - 500  =  1150  after the pumping its amount into C

B contains 150  + 1650 - 650 =   1150   after pumping its amount into C

C contains   500 + 650 =  1150  after receiving  oil from A  and B

CPhill’s comment about the difficulty of this question is from your perspective.

This is not a difficult question for CPhill. He could easily do this while thinking about the Tacos waiting for him in the fridge.

You know, for some reason, I’m hungry for Tacos....

This is very simple:

If 500 litres of oil was pumped from tank A into tank C, then 650 liters of oil was pumped from tank B into tank C.

Now, there's 1150 liters of oil in tank C

Therefore, using the original amount of oil in tank A, we have:      n = 1150 + 500 = 1650 liters
