7
5​

Answer 1

Step-by-step explanation:

98a974

sum of digits should be divided by 9. so sum should be multiple of 9

8+a+7+4 = 19+a =9x

a =9x - 19

if x=1 , a= -10 ---> N/A as digit of no. can't be negative

x=2, a= -1, ---> N/A

x=3, a= 8 ---> yes

x=4, a= 17 ---> N/A as digit cannot have 2 digits

so a = 8
