Answer:
Number of coil in the output is 39938
Explanation:
We have given a step up transformer
Input voltage of transformer, that is primary voltage 
Output voltage, that is secondary voltage 
Number of turns in primary 
For transformer we know that 


As the number of turns can not be in fraction so number of turns in the output coil is 39938
