Q&A - P3 Math

Oh!! Thanks! Thanks! Another question, for P3 Level is it usually just to find 1 missing digit? Will the kid be tested on 2 missing digit instead of 1?

U r welcome!
Usually they asked the number.I think,P3 kid should be able to give the number.Asking missing digit is easier version.For the starting they asked like that then the difficulty go up.

Need help on the following question :


50 children were at a party.
Each boy ate 10 jelly beans while each girl ate 7 jelly beans.
All the girls ate 44 more jelly beans than all the boys.
How many boys and how many grls are at the party?

Other than Guess & Check method, which other method can we use to solve this?

Hi allcc6

Good Morning

There are some similar types of questions in some of our earlier posts, apply the same strategy and you should be able to solve your question.

There are 40 pupils in a class. If each boy is given 3 sweets and each girl is given 5 sweets, the girls will have 56 sweets more than the boys. How many girls are there in the class?

There are 44 cars & bicycles.
There are 128 more car wheels than bicycles. How many car and bicycle are there?

For your question, here’s the solution.

For every increase of 1 boy, the difference in the number of jelly beans drops by 17

350 - 44 ----- 306
306/17 ----- 18

Boys ----- 18
Girls ----- 32

Best wishes

just888,


Thanks for the solution. It’s so easy to understand with the model which I m not good at.

Hi, need help for the following q.


which one of the following numbers, when added to 3178 will allow regrouping of the ones and hundreds?
A) 6732 B)6597 C)5914 D) 5832

TIA

@WCW your answer is wrong. It should be 5832. The TENS and HUNDREDS do not have to be changed, it is the ONES and hundreds
