Answer» A number which is divisible by 2 and 3 or both then the given number is divisible by 6 (i) 324 The given number = 324 Sum of its digits =3 + 2 + 4 = 9 Which is divisible by 3 The given number is divisible by 6 (ii) 2010 The given number = 2010 Sum of its digits = 2 + 0 + 1 + 0 = 3 Which is divisible by 3 The given number is divisible by 6 (iii) 33278 The given number = 33278 Sum of its digits =3 + 3 + 2 + 7 + 8 = 23 Unit digit is 3 which is odd. The given number is not divisible by 6. (iv) 15505 The given number = 15505 Sum of its digits = 1 + 5 + 5 + 0 + 5 = 16 which is divisible by 2. The given number is divisible by 6. |
