Hi,


Please help with the following question:

600 Blue cubes and 1000 Green cubes are kept in Container A. 1000 Blue cubes and 400 Green cubes are kept in Container B. Some cubes are transferred from Container B to Container A. After the transfer, the number of Blue cubes is the same as the number of Green cubes in Container A and the number of Blue cubes in thrice the number of Green cubes in Container B.

a) Find the number of Green cubes transferred from Container B to Container A.
B) Find the total number of cubes transferred from Container B to Container A.


Thanks!

Hi

After transfer :
A = * *
B= # # # #

Total Green cubes = 1400 = * + #
Total Blue cubes = 1600 = * + # # #
So, # # = 200, # = 100, * = 1400 - 100 = 1300

.. i think you can complete the rest..

cheers.

Which Figure is made up of 10,197 X ?

Hi

This doesn't look like a p5/6 question.. more like MO type ..

Fig 1 = 1x3 + 1x2
Fig 2 = 2x4 + 2x2
Fig 3 = 3x5 + 3x2
Fig n = n x (n+2) + n x 2 = n(n+4) = (n+2)^2-4

10197 = (n+2)^2-4
(n+2)^2 = 10201
n+2 = sqrt(10201) = 101
n = 99

Fig 99 made up of 10197 X

cheers.

Hi MathIzzzFun,


Once again thanks for the great help!

The question is given to my P5 kid. By the way, what MO stands for?

Hi Guru, this is concern_mum again, can you help me with question below:


There were 512 tickets to the YOG opening and closing ceremoney for sale. After 3/4 of the opening ceremony tickets were sold, the number of opening ceremony tickets left was 3/7 of the total number of tickets left.

a) How many closing ceremony tickets were there?
b) If the tickets were sold at $80 each, how much money was collected from the sales of the opening ceremony tickets?

Thank you.

Hi,


Can anyone help with this question…my boy and I both tried this question but got a different answer from the answer key :

Garry had twice as many stamps as Henry. After Henry gave away 98 stamps, Garry had 4 times as many stamps as Henry. How many stamps did both of them have at first?

Thanks.

Hi applepie,
This is what I think...
Garry : Henry
2:1
and 2:1 is also equivalent to 4:2 (i.e. total 6 units)
one unit was given away (which is equivalent to 98 stamps) to achieve 4:1 ratio.
Before the one unit was given away, there were a total of 6 units.
Since one unit = 98, the total number of stamps originally was 6 x 98 = 588.

Hope this helps:)

Further amendment:


So Garry had 4x98 = 392 stamps at first
while Henry had 2x98 = 196 stamps at first.
