If the number 72864*@ is divisible by both 8 and 5, then what digits will come in place of * and @ respectively?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 4 and 0.
Divisibility rule of 8:- A number is divisible by 8 if the last three digits of the number are divisible by 8 or are zeros.
Divisibility rule of 5:- A number is divisible by 5 if its last digit is 0 or 5.
The number is 72864*@
So, @ = 0, 5 [if 5 will be the last digit then, it will not be divisible by 8]
So, @ = 0
The digit is 72864*0
Last 3 digits = 4*0
So, for * = 4 [440 is divisible by 8]
Hence,
The value of * and @ are 4 and 0 respectively
