During a sale, Shop A reduces the price by \( 25 \% \) and Shop B reduce the price to by \( 30 \% \). Which Shop is selling the phone at the cheapest price in the sale? Show your workings ( 3 mark)

Round \( 8.91 \) to the nearest tenth.

Hisoblang: \( 0,23 \cdot 10^{-3}+0,02 \cdot 10^{-2} \)

4 If \( A \) is the set of all factors of 36 and \( B \) is the set of all factors of 63 , find: \( \begin{array}{ll}\text { a } A \cap B & \text { b } A \cup B\end{array} \)

If \( a \) and \( b \) are two different integers, and the value of \( \frac{a}{b} \) is also an integer, which of the following statements is true? A If \( b \) is odd, then \( a \) could be even. B If \( b \) is even, then \( a \) could be odd. D The product of \( a \) and \( b \) must be even. E The product of \( a \) and \( b \) must be odd. D Thegers \( a \) and \( b \) cannot be consecutive.
