The correct option is A 96
Since, the tick marks correspond to consecutive integers and it takes four steps to go from x12 to x8. Considering each tick as 1 unit and we know that x8 is greater than x12.
It concludes that x8 is greater than x12 by 4 unit,
i.e: x8=x12+4
Multiplying both sides by 24 gives: 3x=2x+4×24 ; x=96
Hence, option A is correct.
