Someone help me with this pleaseee..
Blababa [14]

So whatever happened does not matter, They are only asking the volume of liquid left in A at the end. Therefore :

Calculation :

B + 120 = 4A

B = 4A - 120 ---------- 1

A - 120 = B ------------ 2

Subtract 2 from 1

B - B = 4A - 120 - A - 120

0 = 3A - 240

240 = 3A

240 ÷ 3 = A

8 = A

Answer :

A = 8
