It is wrong I saw the solution and I found that it has been solved taking 5 ohm resistor....

We infer from the given diagram that the same pattern is followed after every 10ohm resistor. The infinite pattern in parallel as a whole is considered as to be Rx.

Thus, Rx = R + (R||Rx)

Solving for Rx, we get Rx = 1.62R, where R=10ohm.

So we have Rx = (1.62ohm)*(10ohm), which gives Rx=16.2ohm

Therefore, Req = 5 + (10||16.2)

=> 5 + [(10*16.2)/(10+16.2)] => Req = 5 + (162/26.2) which gives Req=11.18 ohm.

Thus, Rx = R + (R||Rx)

Solving for Rx, we get Rx = 1.62R, where R=10ohm.

So we have Rx = (1.62ohm)*(10ohm), which gives Rx=16.2ohm

Therefore, Req = 5 + (10||16.2)

=> 5 + [(10*16.2)/(10+16.2)] => Req = 5 + (162/26.2) which gives Req=11.18 ohm.
