#### Question No 5

A number when divide by 6 leaves a remainder 3. When the square of the number is divided by 6, the remainder is:

Solution!
Let x = 6q + 3.
Then, x2 = (6q + 3)2

= 6(6q2 + 6q + 1) + 3
Thus, when x2 is divided by 6, then remainder = 3.

#### Question No 23

When a number is divided by 13, the remainder is 11. When the same number is divided by 17, then remainder is 9. What is the number ?

Solution!
x = 13p + 11 and x = 17q + 9
13p + 11 = 17q + 9
17q - 13p = 2
q =(2 + 13p) /17
The least value of p for which q =(2 + 13p) /17is a whole number is p = 26
x = (13 x 26 + 11)
= (338 + 11)
= 349

#### Question No 26

What is (999 âˆ’ 99 + 9) Ã· 9?

Solution!
First work out the value of the expression in the brackets and then divide the result by 9. This gives (999 âˆ’ 99 + 9) Ã· 9 = 909 Ã· 9 = 101. Alternatively, we can first divide each number in the bracket by 9 and then evaluate the resulting expression. This gives (999 âˆ’ 99 + 9) Ã· 9 = (111 âˆ’ 11 + 1) = 101.
