A question #9 r and s are two different real number and satisfied (r/s)+[(r+10s)/(s+10r)]=2 find r/s
might be an easy one for you guy :P
Let me just write it using latex: \[\frac{r}{s}+\frac{r+10s}{s+10r}=2\]
hmm \[2 - r/s = \frac{r/s + 10}{10r/s +1}\]
r/s = x
but i am not getting get good roots
can we use latex here??
\[2 - x = \frac{x + 10}{10x +1}\]
oh 4/5and1
i mean i never know we can use it here
so wats ur ans??
sorry these are good roots i made a mistake earlier
4/5 and 1
read the problem carefully LOL
...
and i think i read the problem carefully
It require 2nd equation for solving two variables...
write y in terms of x -.-
I got 4/5 to r=4 and s=5.
ishaan & foolfm, both of you are doing in the correct way. and your answer is nearly correct because r/s=4/5 and 1 truly but from the problem "r and s are two different real number" so the answer should go to 4/5 or 0.8 only LOL
Yes, I was going to post the same thing, when my internet got disconnected. Only 4/5 is the correct answer to this problem.
