Solution :-

We know that the given number \( \overline{66784x}\) is divisible by 9.

And, if a number is divisible by 9 then sum of digits must be a multiple of 9.

i.e., 6 + 6 + 7 + 8 + 4 + x = multiple of 9

x + 31 = 0, 9, 18, 27…..

Here ‘x’ is a digit, where, ‘x’ can have values between 0 and 9.

x + 31 = 36 which gives x = 5.

x = 5
