4

Step-by-step explanation:

Answer 2

Answer:

4

Step-by-step explanation:

first divide 1st 2 digits by 9

i.e. 37÷9 then we will get 1 as a remainder now take 19 and divide it by 9 i.e. 19÷9 we will get 1 as remainder now check if we take 1 in the place of * then after dividing 11 by 9 we will get 2 as a remainder then if we divide 24 by 9 it will not divisible by 9 so 1 will be not there in place of *

now we take 2 in the place of * and then we divide 12 by 9 we will get 3 as remainder then again we divide it by 9 but we can see that 34 it not divisible by 9

continuing this process, taking 3 in the place of * we can see that the whole number will not be divisible by 9.

if we take 4 in the place of * we can see that if we divide 14 by 9 we will get 5 as remainder and then if we divide 54 by 9 we can see that it is divisible by 9.

so in the place of * we have to take the number 4.
