Option 3 : All three

Considering statement (I),

⇒ x = 5

Considering statement (II),

⇒ y = z – 3

Considering statement (III),

⇒ z = 5x – 2

Using information from all three statements,

⇒ z = 5(5) – 2 = 23

⇒ y = 23 – 3 = 20

∴ Required average = (x + y + z)/3 = (5 + 20 + 23)/3 = 48/3 = 16

∴ The question can be answered using all the three statements
