Answer:
B. 80
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
Thus, (120*1/10)-4 ⇔ 120-4 = 8
Now (?*1/10)-4=4 solve it .
Thus, ?*1/10=8⇔?=80 is Our Missing Number .
