Dulwich College 11 Plus Maths Specimen Paper – A by smoothmaths | Jun 21, 2020 | 0 comments Welcome to your Dulwich College 11 Plus Maths Specimen Paper - A TIME allowed for this paper: 60 minutesInstructions Attempt all the questions. Do all your written work on this paper, showing all your working. Calculators must not be used. The numbers in square brackets are the marks available for each part of a question. You must not write in the squares at the bottom right of each page. There are 100 marks in total. 8. Draw the reflection of this triangle in the mirror line shown. (b) Plot the point with coordinates (5,4) onto the axes and label it B. (c) Plot another point, D, and then join ABCD in that order so that you form a quadrilateral shape with one line of symmetry. 15. Each shape in this grid is hiding a particular number so that the three shapes in any row or column add up to the value written at the end of that row or column.Work out the number that should replace the question mark. 20. In four years time, Sam will be twice as old as he was four year ago. Calculate Sam's current age. 21. A packet containing seeds says it produces white, pink and blue flowers in such a proportion that, on average, for every one white flower grown there will be two pink and three blue flowers.(a) I plant some seeds and get three white flowers. Write down how many blue flowers I should expect to grow. (b) I plant a total of 30 seeds in another patch of the garden. Calculate how many white flowers I would expect to get in this patch. (c) In another area of the garden, 24 blue flowers are grown. Calculate how many pink flowers I should expect to find here. 22. (a) Shade in one more section on the grid below so that the overall shape has a single line of symmetry, making your mirror line on the diagram. (b) Now shade two sections in this second grid so that the overall shape has an order of rotational symmetry of two. 23. The diagram below is made from three squares.Calculate the fraction of the larger square that is shaded, giving your answer in its lowest form. Time is Up!
