Dear Student
 
As there is no net accumulation of charge or a vaccancy created during the flow of electrons through the conductor, and the conductor as a whole is always electrically neutral, Hence the number of charge entering any cross section is the number leaving it per second. Hence the current is same through a conductor, or resistors placed in series.
Assume a tunnel to a temple the cross-section of which is narrow at places and large some where having policeman at each step all along. If the number of person at any place should not change with time then the crowd leaving the narrow cross-section will be the crowd entering from a larger cross-section. Thus number of charge carriers moving per unit time is all the same, thus making the same current.

In series combination the voltage(V) across each component is proportional to their resitance(R).
So, V/R=constant …..(1)for all components in this combination.
But V/R=I ….....(2)which is the current through each circuit.
So, from equations (1) and (2) we get that the current throgh each components in series combination is same.
 
Hope you understand my solution.
