Answer:
BI/BII = 1
Step-by-step explanation:
The magnetic field due to a solenoid is given by the following formula:

where,
B = Magnetic Field due to solenoid
μ = permeability of free space
n = No. of turns per unit length
I = current passing through the solenoid
Now for the first solenoid:

For the second solenoid:

Dividing both equations:

here, no. of turns and the current passing through each solenoid is same:
n₁ = n₂ and I₁ = I₂
Therefore,

BI/BII = 1
