sunnyday Posted July 12, 2009 Author Posted July 12, 2009 Thankfully ...when my grandson did his 'mock' papers......he got a really high score for maths...phew! Quote
sunnyday Posted July 12, 2009 Author Posted July 12, 2009 Oh here's another 'good' one.... Here are five scores in a cricket match: 11, 23, x, 44, 7. The mean score was 18. What is the value of x? Quote
mundia Posted July 12, 2009 Posted July 12, 2009 This is giving my old brain a good workout, but Ill let someone else reveal the answer to that one! Quote

sunnyday Posted July 12, 2009 Author Posted July 12, 2009 Any more - or are you tired of my game? Quote
sunnyday Posted July 12, 2009 Author Posted July 12, 2009 what else can you test us with? hmmm.......the other subjects are too easy.......must be I can do them So....... more maths..... Mike thought of a number. He halved it, then added 9. The answer was 45. What number did Mike think of? (Please show 'working out' process! I added that bit! Quote
Motherclanger Posted July 12, 2009 Posted July 12, 2009 Absolutely rubbish at Maths ! Trouble is got to take my Level 2 in Numeracy and Literacy soon so need all the help I can get ! Motherclangerx Quote
Marion Posted July 12, 2009 Posted July 12, 2009 sorry I'm rubbish at working out but here goes 45-9 =36 x 2 =72 Quote
Guest Posted July 12, 2009 Posted July 12, 2009 it is 72 but im sure how i worked it out was far too complicated Quote
sunnyday Posted July 12, 2009 Author Posted July 12, 2009 72 I was so tempted to be really naughty and say.......sorry Marion that's wrong! But I couldn't do it!!! Quote
sunnyday Posted July 12, 2009 Author Posted July 12, 2009 OK.......... Jane is drawing a plan of her house. Her scale is 4cm to 5cm. The hall is 10.5m long. How long is the hall on her plan? Quote
mundia Posted July 12, 2009 Posted July 12, 2009 Yes Panders, work backwards. the answer is 45, take away the 9 (opposite to what was done n the question which was to add9). Then double the answer, again the opposite of the halving in the question. Does that make sense. Ok just for Panders please. I am thinking of a number. I take away 4 then double it. I get 16. What number did I start with? Quote
Motherclanger Posted July 12, 2009 Posted July 12, 2009 36+36 = 72 36+9 =45 Is this right ? Told you I'm rubbish ! My 12 year old son has just told me he's embarassed because I've taken sooo long to find the answer ! My reply there's a lesson for you, make sure you do well at school the first time round !

sunnyday Posted July 12, 2009 Author Posted July 12, 2009 8.4 cm Er....seriously now .......how did you get there? Are you feeling really sorry for my darling grandson? Quote
sunnyday Posted July 12, 2009 Author Posted July 12, 2009 12 Is that Jane's hall? If so.... no.....8.4 Quote
mundia Posted July 12, 2009 Posted July 12, 2009 Well done Panders, easy isn't it? Sunnyday, the scale in 4/5 so all you need to do is find 4/5 of 10.5, ie divide by 5 (2.1) then muliply for 4 to give 8.4 Quote
Marion Posted July 12, 2009 Posted July 12, 2009 Er....seriously now .......how did you get there? Are you feeling really sorry for my darling grandson? 10.5 /5 =2.1 x 4 = 8.4 sorry I'm one of those annoying people who just see the answer Quote
HappyMaz Posted July 12, 2009 Posted July 12, 2009 Well done Panders, easy isn't it? Smugness is ill-becoming mundia! You know how mathematically challenged I am!
