The number which is divisible by 6 is a multiple of 6.
Let x by any integer.
6x is always divisible by 6.
⇒6x+4 will result in a remainder of 4.
The largest two digit number =99
∴6x+4≤99
⇒6x≤99−4
⇒x≤956
⇒x≤15.8¯3
∴ The largest possible value of x is 15.
Hence, the required number is 15×6+4=90+4=94.
