Answer:

Step-by-step explanation:

37y37 is divisible by 3.

Now, the divisibility rule of 3 is that  the sum of all the digits of the number should be divisible by 3.

So, 3+7+y+3+7 should be divisible by 3.

   ∴20+y should be divisible by 3.

Now, the nearest number divisible by 3 is 21.

So, 20+y=21

∴y=1.
