1. (iii) Since 1/5 and 6/5 both gives remainder 6, hence either 1 or 6.

2. (i) Since the factor of 9 is 3 hence any number if divisible by 9 must be divisible by 3.

3. (ii) If it is assumed that 3a64 is a number divisible by 9. Hence it must be first

divisible by 3.

3 + a + 6 + 4 = (13 + a) must be divisible by 3.

If we substitute a with 1, 3 or 4 we get the value of (13 + a) = 14, 16 and 17

respectively. Since none of these is divisible by 3.

And if we substitute a with 2, we get (13 + a) = 15 which is divisible by 3. Hence

Ans is 3.

4. (i) 0, If we assume 1x2y3z to be a number divisible by 9, then it must be divisible by

3 (as above).

1 + x + 2 + y + 3 + z = (9 + x + y + z) must be divisible by 9.

Since 9 is already divisible by 9, hence x + y + z can be 0.

Ans is 0.

5. (ii) 3, Since 28221 is an odd number, hence it cannot be divisible by 2 or 6 (since it

has a factor 2 in it). Since 2 + 8 + 2 + 2 + 1 = 15, hence it is surely divisible by 3. And

if we divide 28221 by 3, we get 9407. Since9407 is not divisible by 3 Since 9 + 4 + 0

+ 7 = 20 is not divisible by 3. Hence, 28221 is not divisible by 9.
