Water Tank Flush Tank Connector Puzzle - with Answer

Puzzle for Genius - PLASTO Water Tank, Flush Tank and Cork Math Puzzle.

ANSWER

58 is the Answer

Explanation
Equation 1: (4+6) + (4+6) + (4+6) = 30 (There is a connector at the bottom of each tank; Connector = 6 from equation 3)
Equation 2: 5 + 5 + 5 = 15
Equation 3: (6+6) + 6 + 6 = 24 (There are 2 cork in first place if look closely)
So Water Tank = 4; Flush Tank = 5 & Connector = 6
Equation 4: (6x3) + (5x2) x (4) = 58 (If you look closely you can see the number 3 in connector and number 2 in flush tank in the last equation. So connector is multiplied by 3 and flush tank is multiplied by 2)
