Re: Maths made easy =) stuck sumwhere?Ask ur doubts here!!

i think that the answer is 20
u can solve this question by drawing a venn diagram
Here is the solution:-
11+12+6+7+3x=60
therefore x=8
nowww.....
add 8+6+6=20
Therefore pills containing Vitamin A=20

@HyDraZin3= You missed the pills that contain only Vitamin A. And you have to add 8 twice and not 6 twice. So 8+8+6+12=34..
The total number of pills containing Vitamin A are 34.
You should use venn diagram for this question. It'll make it very simple.

Waalaikumassalam!! :)

No, specimen papers are published when they change the pattern/style of the questions. I just checked the CIE Website, the latest specimen paper published was the Paper 4 in the year 2009 ! :)

Check the link above to access the latest specimen paper.
Hope this helps! :)
Thanks for your query, Jazak Allah Khair!
Please do not hesitate if you have any more questions! :)

Re: Maths made easy =) stuck sumwhere?Ask ur doubts here!!

Please help.

Question:

f:x -> (x+2)/a; a not 0. g:x -> 2x^2+1. If gf(x) = 2x^2 - bx +9, find the values of a and b.

The answer is a=1, b= -8 and a= -1, b= -8


So here is what I worked out so far:

gf(x) = 2 ( (x+2)/a )^2 + 1 = 2x^2 - bx + 9
therefore 2 ( (x+2)/a )^2 = 2x^2 - bx + 9 - 1
so then 2 ( (x+2)/a )^2 = 2x^2 - bx + 8

but how do i solve for a and b when there is only 1equation to work with?
