The parallel combination of a 470 
resistor and a 1.5 k resistor is in series with the parallel combination of five 1 k resistors. The source voltage is 50 V. The percentage of the load current through any single 1 k resistor is

Thank you for the explanation.

You are right @Shashank.
But can you tell me what is the formula if there is not same resistance in parallel?

@Priya,
Where does that 1/4 comes from I am not getting that?

@Rohith, Am Not getting your Formula, Could you please expand Once again ?

Of course @Meena you are right.
But this simple and quick method is only applied when all the resistors are of same value. Otherwise you can't applied when resistors are of different values are given.

@Meena.
Exactly your right for same set of resistors. And even we can calculate the same in for different resistors values.

@Meena.
You are wrong in parallel current through all branches is not same :).
You are getting the right answer because all resistors are same value so the currents drawn by them is also same :).

Then you need to do as explained by @Priya.

What about if the resistors connected in parallel are not of same value?

I am 100% agree with the solution given by Meena, it is the simplest & quick way of calculation. The total current flowing out from the first parallel combination will flow in the second combination but will get divided in to five equal parts so each part of current will be i/5th of the combination(2nd) total input current which will be 1/5th i.e..2 or.2*100 = 20%.
