Answer 2

Answer:

y = 4

Step-by-step explanation:

Given number is 72y5

Let's see some definition

Divisibility of 9 : When sum of digits of number devisible by 9 ,then whole number can be devisible by 9.

Now, find their sum

=> sum = 7 + 2 + y + 5

=> sum = 14 + y

The number which more than 14 devisible by 9 is 18.

Therefore, 14 + y = 18

=> y = 18 - 14

=> y = 4

Therefore value of y = 4
