There are two numbers. When one is added to each of the two numbers, their ratio is 1 : 2. When 5 is subtracted from each of them, their ratio is 5 : 11. Find the numbers.

Question

anonymous · Answer

x+1/y+1=1/2
so 2x+1=y+1
so y=2x

anonymous · Answer

x-5/2x-5=5/11,
11x-55=10x-25 so x=30

anonymous · Answer

so y =2x then y=60?

i don't know how to explain this to you but good effort on your work :)

anonymous · Answer

no no...$$\frac{ x+1 }{ y+1 } = \frac{ 1 }{ 2 } \Longrightarrow 2x + 2 = y + 1$$

anonymous · Answer

oh yes.i made a mistake there .3q @PFEH.1999

anonymous · Answer

and so try it again...

anonymous · Answer

so 35 n 71

anonymous · Answer

i will always make mistake by not multiplying other one.

anonymous · Answer

oh no problem :) if u practice a lot you won't  make mistakes :)

anonymous · Answer

and so u should notice this:
$$\frac{ x-5 }{ y-5 } = \frac{ 5 }{ 11 }$$

anonymous · Answer

yes

anonymous · Answer

35 n 71

anonymous · Answer

let me check

anonymous · Answer

above i gave the answer

anonymous · Answer

doesn't seem correct ... let me check it again.

anonymous · Answer

maybe i made a mistake.

anonymous · Answer

correct ;) x=35 and y=71 i made a mistake at first ;)

anonymous · Answer

see=> y=2x+1.so x-5/2x+1-5=5/11

anonymous · Answer

same as me

anonymous · Answer

ok then ;)

anonymous · Answer

do u still have any problems?

anonymous · Answer

yes .i will post if i have doubt.3q @PFEH.1999 .i need trigonometry notes.u gave formula for tan(a+b)=tana*tanb/1-tana*tan b.thats simple but i dont understand c2,c1,b mentioning in triangle for the sum tan(-15)
