Explanation:

in series

1/15 + 1/150 = 1/R

=>11/150 = 1/R

=> R = 150/11

Explanation:

Two wires connected in series

R= R1+R2= 25 ohms…….(1)

Again same wire connected in parallel

R=R1R2/R1+R2 =6 ohms………(2)

By equation (1)

R2= 25- R1

Put this in sa (2)

R1(25-R1)/R1+25-R1=6

25R1-R1^2=6×25

R1^2-25R1+150=0

R1= 15ohms or 10 ohms

R2= 10ohms or 15 ohms.
