Hi Jieheng!



Thank you! I need sometimes to digest this solution and explain to my kid. :oops:

Hi bookwormkids ,

You are welcome.

Hi


Hope this helps.

You may use a heuristics known as \"working backwards\" to solve this question.

As usual, I've drawn more models than necessary to show the flow of events.

Best wishes.

I need some help. My DD asked me her school maths last night. I really blurred.


The question:

The boys and girls together 258 went in to the hall. When 1/3 of the boys came out of the hall, another 22 girls went in. At the time, the boys and girls will be in equal amount.

Please find out how many boys are there in the first place.

Please advise. :?
