as we know potential  remains same in parallel circuit

use the formula P= V2 / R, this will give first resistance,

now use two equations i1 + i2 = 10 , where i1  is the current is first branch and i2 in second, and use the second equation

i1 R1 = i2 R2 , from this find second resistance and again use the formula

P = V2 / R put the values of V and R and find the anwer.
