Hi,


I need help for the following :

Jan and Kay had equal number of sweets and equal numbers of chocolates. Jan ate 12 sweets and Kay ate 18 chocolates and then the ration of Jan's sweets to chocolates became1:7 and the ration of Kay's sweets to chocolates became 1:4. How many sweets did Jan have at first ?

The answer given is 34 sweets.

Tianzhu,

Thank you very much

Hi Tianzhu,


Thank you so much for providing the MD. I understood very clearly for the Hansel and Gretel solution.
My son and I have benefitted greatly not only for those questions that we’ve posted as well as from other’s postings.


Thanks for sharing !

Hi Tianzhu,


:thankyou: for sharing the sweets & chocolate questions pictorially. DD used models to solve this question but yours is definitely more appealing. Wow...you really have a flair for making maths look easy and interesting. Thanks for all your efforts. :salute:

oops...didn't realise that Tianzhu had already posted the solution. Great pics! I'm hungry simply looking at the pics.

just an aside: seem to have a number of similar or the same questions. Either lotsa children are from particular school/s or the questions are recycled? haha!

cheers!
