Answer:

B. 80

Step-by-step explanation:

According To Question, We Have

(180,14) (120,8) (? , 4) (220,18)

  • it Clearly Visible That ( 180*a+b=14 ) only Possible when we Put a=1/10 & b=-4. Thus, (180*1/10)-4 ⇔ 18-4 = 14
  • Same For All (120*a+b=8)

        Thus, (120*1/10)-4 ⇔ 120-4 = 8

Now (?*1/10)-4=4 solve it .

Thus, ?*1/10=8⇔?=80 is Our Missing Number .
