The ratio of the number of teeth on the
                                           cogs can be expressed as a ratio of their
                                           circumference which in turn can be expressed
                                           as a ratio of their radii.
                                           X:Y:Z = 8 : 4 : 12 = 1 : ½ : 3/2
                                           Cog X has twice the number of teeth as cog Y,
                                                                                                     Algebra and

                                           cog Y must make 2 revolutions.
                                           Cog X has 2/3 of the number of teeth of
                                           cog Z, so when cog X makes a complete
                                           revolution, cog Z makes 2/3 revolutions. When
                                           cog X makes 15 revolutions, cog Y makes 30
                                           revolutions and cog Z makes 10 revolutions.

                                           The difference between ¾ and ½ is ¼.
                                           Therefore, if we turn the sign ¾ turn clockwise,
                                                                                                      Space and
            9                   A          , then ½ turn anticlockwise, , then the                                 Hard
                                                                                                      Geometry
                                           result will be the same as just turning the sign
                                           ¼ turn clockwise.

                                           If a cube has a volume of 343 cm3 then its edge
                                           length is 7 cm. There are 12 edges on a cube,
          10                   84                                                                   Measurement      Hard
                                           so the total length of the edges is 7 × 12 =
                                           84 cm

    LEVEL OF QUESTION KEY SOLUTION STRAND DIFFICULTY The temperature of an ice-cream is very close to the freezing point of water (0 °C). Noticing 1 A Measurement Easy the given scale, the closest point to 0 °C is option A. Number and 2 C Multiplying 5 by 50 gives 250. Easy Arithmetic This number should have 6 digits. If we write it using expanded notation, we should have Number and 3 B Easy 400 000 + 600 + 2. In other words, it is Arithmetic 400 602. Reading the code from left to right from the upper left corner and using the key provided, Number and 4 C Easy option C is the only code that shows correctly Arithmetic all digits of the given number. The 3D shape is made of four rectangles and 5 A Measurement Medium two pentagons. Trent made his pattern by skipping squares systematically by 2, then 3, then 4, then 5 squares. Number and 6 C Medium Following this pattern, he will skip 6 squares Arithmetic to shade the next square. Therefore, the next shaded number in Trent’s pattern will be 26. Convert hours to minutes and m to cm first. The snail travelled 1.5 m in 4 hours. That is equal to 150 cm in 240 min. Number and 7 B Hard 150 150 Distance travelled in 1 min = cm × 160 Arithmetic 240 240 150 150 Distance travelled in 160 min = × 160 cm 240 240 = 100 cm ICAS Mathematics Practice Questions Paper E © EAA

    The ratio ofthe number of teeth on the cogs can be expressed as a ratio of their circumference which in turn can be expressed as a ratio of their radii. X:Y:Z = 8 : 4 : 12 = 1 : ½ : 3/2 Cog X has twice the number of teeth as cog Y, Algebra and 8 B so when cog X makes a complete revolution, Medium/Hard Pattern cog Y must make 2 revolutions. Cog X has 2/3 of the number of teeth of cog Z, so when cog X makes a complete revolution, cog Z makes 2/3 revolutions. When cog X makes 15 revolutions, cog Y makes 30 revolutions and cog Z makes 10 revolutions. The difference between ¾ and ½ is ¼. Therefore, if we turn the sign ¾ turn clockwise, Space and 9 A , then ½ turn anticlockwise, , then the Hard Geometry result will be the same as just turning the sign ¼ turn clockwise. If a cube has a volume of 343 cm3 then its edge length is 7 cm. There are 12 edges on a cube, 10 84 Measurement Hard so the total length of the edges is 7 × 12 = 84 cm Level of difficulty refers to the expected level of difficulty for the question. Easy more than 70% of candidates will choose the correct option Medium about 50–70% of candidates will choose the correct option Medium/Hard about 30–50% of candidates will choose the correct option Hard less than 30% of candidates will choose the correct option ICAS Mathematics Practice Questions Paper E © EAA
