# If abc is a three

Answer :

Since abc is a three digit number

General form of abc is abc = 100a + 10b + c

Now; abc – a – b – c = 100a + 10b + c – a – b – c.

abc – a – b – c = 100a – a + 10b – b + c – c.

abc – a – b – c = 99a + 9b.

abc – a – b – c = 9( 11a + b).

abc – a – b – c is divisible by 9 because 9 is one of its factor.

Hence the correct option is (a).
