Answer:
The number of loops in first coil is 64
Step-by-step explanation:
Given :
Induced emf in first coil
1.23 V
Induced emf in second coil
4.56 V
No. loops in second coil

We have to find no. loops in first coil
Apply faraday's law to each coil,

Now compare above equation,

So loops in first coil is,


≅ 64
Therefore, the number of loops in first coil is 64
