Dear Pushkar
Add x, y,z respectively in the three equations.
x(x+1)=y(y+1)=z(z+1)=x+y+z
1/(x+1)=x/(x+y+z).......(1)
Similarly
1/(y+1)=y/(x+y+z)........(2)
1/(z+1)=z/(x+y+z).........(3)
Add eqn. (1), (2) & (3)
We get answer is 1
x(x+1)=y(y+1)=z(z+1)=x+y+z
1/(x+1)=x/(x+y+z).......(1)
Similarly
1/(y+1)=y/(x+y+z)........(2)
1/(z+1)=z/(x+y+z).........(3)
Add eqn. (1), (2) & (3)
We get answer is 1
