Water in A = X + 150
Water in B = X

Situation 2:
(x+150−20) = 4∗(x−20)
x+130 = 4x - 80
3x = 210
x = 70

Total capacity = x+(x+150) = 70+70+150 = 290

Therefore, the correct answer is Option A

Let x be the number of gallons in Aquarium B -> number of gallons in Aquarium A is x+150

If 20 gallons are removed from both the aquariums then the number of gallons in A is 4 times number of gallons in B

$$x+150-20 = 4*(x-20)$$

x = 70

Total capacity = x+x + 150 = 290

Hence Option A

Let A & B be the capacity of Aquarium A & B respectively.

We have A = B + 150.....(I)

Now 20 gallons is removed from each tank & new relationship between A & B is

A - 20 = 4*(B - 20)........(II)

Solving (I) & (II), we get

B = 70 & A = 220

Hence Combined capacity, A + B = 290 gallons
