Hi Ksoh3000,

The two page numbers must be consecutive.
Product of the two = 72
So by a number \"feel\" it should be = page number 8 and 9

PS- for P3 Maths there is a separate thread under Primary 3. Please post there. Thanks.

Can somebody help?


The cost of 7 erasers and 3 rulers is $5.05
The cost of 2 erasers and 7 rulers is $3.95
Find cost of 2 erasers and 2 rulers.

Find cost of 2 erasers and 2 rulers.

Should the qn be 3erasersn 7 rulers=3.95

Then u simply add to get 10erasers n 10rulers=9.00
So 1 eraser n 1 ruler=0.90

If based on qn post the kid must know how to multiply decimal number n division of double digit number, at this point of time, the skill requirement is too much for p3 kid to handle.... Cheers

Oh really? Is 3 erasers and 7 rulers…


The answer given was $2, so there’s typo error in the test paper?
