Step-by-step explanation:
Given voltage of primary coil is 
And voltage of secondary coil is 
A transformer is a device that contains primary and secondary coil. These coils are mounted on soft iron. The change in voltage depends upon the number of turns of primary coil
and secondary coil
.
Following equation represents the relation between them.

Then, ratio of the number of wire turns on the primary coil to the number of turns on the secondary coil is

The answer I got was 2,423,000 million square miles. If there is a choice that says that then it’s the answer. If not, I’m probably wrong.
Hope this helps!
