I1 = 0.26 W ; I2 = 0.46 W; I3 = 0.92 W. These are my answers.

I think that the 0.52 W is wrong and that 0.46 W should be the answer.
So, it should be P1=0.26 P2=0.46 & P3=0.23.
So, it should be P1=0.26 P2=0.46 & P3=0.23.

Find out total resistace i.e. 11/3kohm
Find out current i.e. 59/(11/3)mA= 16.09mA
Now by formula i2R find out power dissipated

For the total resistance I got: 3666.67 Ohms.
For I1= 16.1 mA squared this & times by R1 --> PDr1= 258 mW.
For I2= 10.73 mA squared this & times by R2 --> PDr2= 460 mW.
For I3= 5.37 mA. squared this & times by R3 --> PDr3= 230 mW.
I am getting the right answers for P1 & P3. For P2, I am a little off. Am I doing something wrong?
Can someone explain me?

How to solve the question?
My answer for P2 was 0.46W, am I doing something wrong?
My answer for P2 was 0.46W, am I doing something wrong?

Yes, I got the answer for P2 is 0.46W.
Can someone explain the correct method?

I also calculated 0.46 W.
I also put this into circuit simulator, same result.
