  This is a tricky Maths question that Karishma shared:
     There are 7 girls in a bus with no driver.
      Each girl has 7 backpacks.
     In each backpack, there are 7 big cats.
     For every big cat, there are 7 little cats.
     How many legs are there in the bus? (Not the wheels)
        Can you answer it?

    7x2=14=no. of girls legs
    each girl=7x7-49 big cats 49x7=343 small cat
    49+343=392
    392x7=2744
    2744+14=2758

      Good try, Meng Yuen...Why did you add 49 to 343?

    Miss Zhou,the paper has the answers on it so you can tell them the answers if needed
    And Meng Yuen,both your answers are wrong.

    there are 7 girls, so 7x2 (2 legs per girl)= 14
    7 girls x 7 back packs= 49 backpacks
    49 backpacks x 7 cats= 343 big cats
    343 x 4 legs (on the big cats)= 1372
    343 big cats x 7 little cats= 2401 little cats
    2401 little cats x 4 legs= 9604 legs

    so then 14 legs of girls +1372 legs of big cats +9604 legs of small cats= 10990 legs in total
