R/4 Ohms/wire.
Rb = 1/4 * R/4 = R/16 or 1/16R = Resistance of the bundle.
A piece of wire of resistance, R and uniform cross sectional area, A is cut into four equal parts and bundled together to form a thicker wire. The resistance of the bundled wire is:
A 16R
B 1/4R
C 4R
D 1/16R
It's either 16 or 1/16 im not sureee. So I need help for the working part! Thanks :)

As R is inversly propotional to area so resistance will be
R= 1÷A
R= 1/4R
R= 1÷A
R= 1/4R
