what will be the ratio of x y S1 x y-8 S2 x 2 y 2

x^2=y^2
(y-8)^2=y^2
y^2+64-16y=y^2
16y=64
y=4
so, x=-4
x:y=-4:4=-1:1

only S2. Using S1 we can not find x:y.
10 years agoHelpfull: Yes(8) No(10)
both st together is reqd.
10 years agoHelpfull: Yes(4) No(2)
both statement together are not sufficient..
10 years agoHelpfull: Yes(3) No(7)
only s2 is sufficient..
1-take sqre root both side and bring variables one side of the eqn.
10 years agoHelpfull: Yes(3) No(1)
statement 2 : x^2=y^2
which gives x^2/y^2=1
(x/y)^2=1
x/y=1^1/2
x/y=1
so, statement 2 should alone be sufficient enough to find the ratio x/y.
10 years agoHelpfull: Yes(1) No(1)
either one statement can find the ans

Ratio canot b negetive

x=-4;y=4;
(-4)^2=(4)^2;
ratio
-1/1;
10 years agoHelpfull: Yes(0) No(0)
from s2 x^2 = y^2.....put the value of x from S1 then
(y-8)^2 = y^2.... we will get y = 4
Put the value of y in S1 then we will get x = -4
now, x/y = (-4/4)= -1
So Both statement is required to get the answer.
10 years agoHelpfull: Yes(0) No(1)
ans:x:y= -4:4 or -1:1
10 years agoHelpfull: Yes(0) No(0)
with the help of 2nd equation we can solve the question.
so ans is statement s2 only.
x^2=y^2
x^2/y^2=1
taking sq.root
x/y=1/1
so ratio will be 1:1
10 years agoHelpfull: Yes(0) No(0)
Ans: x/y=-1
9 years agoHelpfull: Yes(0) No(0)
S2- X^2 = Y^2
X= Y
X/Y = 1
HENCE S2 IS ONLY ENOUGH TO ANSWER THE QUESTION
9 years agoHelpfull: Yes(0) No(0)

what will be the ratio of x:y

S1: x=y-8

S2: x^2=y^2
