The H.C.F. of `a/b , c/d , e/f` is equal to (a) `(LCM of \ a ,\ c ,\ e)/(HCF of\ b ,\ d ,\ f)` (b) `(HCF of\ a ,\ c ,\ e)/(LCM of\ b ,\ d ,\ f)` (c) `(HCF of\ a ,\ c ,\ e)/(HCF of\ b ,\ d ,\ f)` (d) `(a c e)/(b df)`

If a,b,c,d,e,f are in ..., then e-c is equal to

If a/b=c/d=e/f=3/4 , then (a+c-e)/(b+d-f) is:

If (a)/(b) = (c )/(d ) = (e )/(f) = (3)/(4) , what is the value of (a+c +e )/( b+d +f) ?

Statement (A): L.C.M of 2^2 xx 3^3 xx 5 , 2^3 xx 3^2 xx 2 xx 3 xx 5 xx 7 is 500 ; Statement (B): L.C.M of a/b,c/d,e/f is (L.C.M of a,c,e)/(H.C.F of b,d,f) Statement (C): H.C.F of i/m,n/o,p/q is (H.C.F of I,n.p)/(H.C.F of m,o,q)

(a)/(b) = (c)/(d) = (e)/(f) = k(a, b, c, d, e, f gt 0) then

If a, b, c, d, e, f are in A.P., then e – c is equal to

If a,b,c,d,e, f are A. M's between 2 and 12 , then find a + b + c +d + e +f.
