Answer:

Ans. is 6 and 3.

Explanation:

Let, a1 and a2 be 2 resistances.

by given conditions,

a1+a2=9 and a1a2/a1+a2=2.

a1a2/9=2 , hence a1a2=18.

a1=18/a2

putting this in a1+a2=9,

We get,

a2²-9a2+18=0

a2(a2-3)-6(a2-3)=0

a2=6 or a2=3

a1=18/a2

therefore,

a1=3 or a1=6.

Hence, 2 resistances are 6 and 3.
