All the three are equal in number
None of these

Discuss Question

Answer: Option D. -> All the three are equal in number
Answer: (d)
Adjacent symbol - letter pairs are ∂ L 3 @ Y, ÷ D,β H.
So, X = 4.
Adjacent letter - number pairs are L 3, E 6, F 4, H 7.
So, Y = 4.
Adjacent number - symbol pairs are 3 @, 8 ®, 4 β, 7 ©.
So, Z = 4.
Thus, X = Y = Z.
