Grey Black White Dots Puzzle with Answer | "Ithil Naalamathe Utharam Enthaanu"

ANSWER


61 is the Answer

Explanation
Let us assume;
x = Grey Dot
y = Black Dot
z = White Dot

From Coulmn 1 & 2:
Equation 1: 3x + y = 56
Equation 2: x + 3y = 48

On solving Equations 1 & 2, we get:
y = 11 
x = 15

From Coulmn 3:
Equation 3: 2z + x + y = 66
=> 2z + 15 + 11 = 66
=> z = 20

Solving Coulmn 4:
2x + y + z =?
=> (2 x 15) + 11 + 20
=> 61
