If `a/(b+c)=b/(c+a)=c/(a+b)=K` , then the value of `K` is `+-1/2` (b) `1/2` or `-1` (c) `-1` (d) `1/2`

If (a+b)/(c)=(b+c)/(a)=(c+a)/(b)=k, then k is equal to 0 b.1 c.2 d.a+b+c

If log_(a)b=1/2,log_(b)c=1/3" and "log_(c)a=(K)/(5) , then the value of K is

If a=bc and c=a-b, then the value of a is b^(2)-1( b )(b^(2))/(b-1) (c) (b)/(b-1) (d) None of these

If a+b=2c, then the value of (a)/(a-c)+(b)/(b-c) is (1)/(2)(b)1(c)2(d)3

If 1.125xx10^(k)=0.001125, then the value of k is: -4(b)-3(c)-2(d)-1

If (a)/(3)=(b)/(4)=(c)/(7), the value of (a+b+c)-:c is (a) (1)/(7)(b)(1)/(2)(c)2(d)7

If a,b,c are consecutive positive integers and (log(1+ac)=2K, then the value of K is log b(b)log a(c)2(d)1
