If `a/x+y/b=1` and `b/y+z/c=1` , then `x/a+c/z` will be equal to: (a) 0 (b) `b/y` (c) `1` (d) `y/b`

If a=b^(x),b=c^(y) and c=a^(z) , then the value of xyz is equal to (a)-1 (b)0 (c)1 (d)abc

If a^(x)=b^(y)=c^(z)andabc=1 , then the value of 1/(x)+1/(y)+1/(z) will be equal to

If (x)/(y+z)=a;backslash(y)/(z+x)=b and (z)/(x+y)=c then (1)/(1+a)+(1)/(1+b)+(1)/(1+c) is equal to (a) 2( b) 3(c)6(d)x+y+z

If a=b^(x),(:b=c^(y) and backslash c=a^(z), then the value of xyz is equal to a.0 b.1 c.-1 d.abc

If (b)/(y) + (z)/(c) = 1 and (c)/(z) + (x)/(a) = 1 , then what is (ab + xy)/(b x) equal to ?

Which of the foliowing statement(s) is/are true? (A) If a^x =b^y=c^z and a,b,c are in GP, then x, y, z are in HP (B) If a^(1/x)=b^(1/y)=c^(1/z) and a,b,c are in GP, then x,y,z are in AP

If (b + c) (y + z) - ax = b - c, (c + a) (z + x) - by = c - a and (a + b) (x + y) - cz = a - b , where a + b + c ne 0, then x is equal to a) (c + b)/(a + b + c) b) (c - b)/(a + b + c) c) (a - b)/(a + b + c) d) (a + b)/(a + b + c)
