I can start by stating the obvious: SX/QX = 2/3.

dw:1350051539893:dw we can easily see a/(a+b+c) = 2/5 b/(a+b+c)= j/5l c/(a+b+c) =(3l j)/5l we need to find numerical value of b/(a+b+c) where, we know that a/(b+c) = 2/3 any help ?

Here's what I got so far. I let PZ=2 and ZQ=3 since that satisfies the ratio. XQ/ZQ = SX/PZ > XQ/3 = SX/2 XQ/ZQ = 2/3 > XQ = 2 SX/PZ = XQ/ZQ > SX/2 = 2/3 SX = 4/3 SX+XQ = 10/3

XQ/ZQ = 2/3 > XQ = 2 will that be right to conclude ?
 one year ago

shubhamsrg Group TitleBest ResponseYou've already chosen the best response.0
am saying this since this would be another assumption based on an earlier assumtion that PZ=2 and ZQ = 3

CliffSedge Group TitleBest ResponseYou've already chosen the best response.0
I think so, that's what I got. I'm still playing around with the proportions to find XY or YQ..
 one year ago

CliffSedge Group TitleBest ResponseYou've already chosen the best response.0
That wasn't an assumption, that was an arbitrary choice. There's no restriction on what PZ and ZQ are as long as they satisfy the ratio.
 one year ago

shubhamsrg Group TitleBest ResponseYou've already chosen the best response.0
but, in generailty, we have PZ = 2m and ZQ = 3m you assumed m=1 ,,fair enough now XQ/ZQ = 2/3 XQ = 2n => ZQ = 3n this came from the fact m =1// now will that be right in saying n=1 also when m=1 already ?

If you're using 2m and 3m and 2n and 3n, just because you can choose m=1 at first, that doesn't make n=1.

shubhamsrg Group TitleBest ResponseYou've already chosen the best response.0
thats what am saying,,but you took both m and n = 1 ..

I never bothered with m or n at all. I set PZ=2 and ZQ=3 and the rest followed.

gotcha !

PZ=2 and ZQ = 3 made you reach till XQ/ZQ = 2/3 but XQ = 2 and ZQ=3 i guess wont be right..

I wasn't saying 5/3 was the answer, I was saying that if RZ divides PQ in ratio 2 to 3 then Y divides SQ in ratio 2+3 to 3 (imagine RZ sliding along QP until it becomes a diagonal of the //gram)

those two are sufficient to get to 9/40

am sorry but am still unable to @ganeshie8 :

CliffSedge Group TitleBest ResponseYou've already chosen the best response.0
I was able to get it using estudier's SY/YQ=5/3. SY + YQ = SQ = 10/3 SY = 10/3  YQ (10/3/YQ)/YQ = 5/3 > YQ=5/4 SY = 25/12 XY = SYSX > XY = 3/4 XY/SQ = (3/4)/(10/3) = 9/40. QED.
