If I'm reading this right, you have two resistors in series followed by three in parallel, with all the individual resistances known (2.5, 0.25, then 4, 5 and 2 ohms). Voltage is given, so the problem is to solve for the current? You need to find Req for the parallel resistors. The formula is: $\frac{1}{R_{eq} }= \sum \frac{1}{R_i}$ Does this help?

@telliott99 thx

how is will be the result

Do I have the correct numbers? Is it 4 or 40?

{5||2||40}+2.5 0.25=4.129ohm to find i2,i2=[(40||5)/{(40||5)+2}]*100/4.129=16.56(approx)

@moha_10 hi check that lesson for better understanding of resistors in parallel http://utwired.engr.utexas.edu/rgd1/lesson05.cfm

u can also use ORCAD to solve that!
