If we will connect the resistors 2ohms, 3ohms, 5ohms in series and the 10ohms resistance parallel then we get equivalent resistance of 5 ohms.
The equivalent circuit is,
R equivalent for the series connection is,
The equivalent resistance is 5 ohms.
So your friend is saying true.
I believe I seen on google if you go to Mather
