`If   a + 1/b = 1 and b + 1/c = 1` , then show that   `c + 1/a = 1`

If a + 1/ b =1 and b+1/c =1. then c+ 1/a is equal to

If a-(1//a) = b, b-(1//b) =c and c - (1//c) = a , then what is the value of (1//ab) + (1//bc) + (1//ca) ? यदि a-(1//a) = b, b-(1//b) =c तथा c - (1//c) = a है, तो (1//ab) + (1//bc) + (1//ca) का मान क्या है?

If a=-10,b=1 and c=1 , Show that a -: (b+c) != (a -:b) + (a-:c)

If a is the A.M. between b and c, b the G.M. between a and c, then show that 1/a,1/c,1/b are in A.P.
