Explanation / Answer

Here for given figure,

R1 = 45 ohm

All for resistors are in parallel.

So resistor of parallel combination of 25 and 12 ohm = 25*12/(25+12) = 8.1 ohm

and resistor of parallel combination of 45 and 5 ohm = 45*5/(45+5) = 4.5 ohm

Then finally

resistor of parallel combination of 8.1 and 4.5 ohm = 8.1*4.5/(8.1 + 4.5) = 2.9 ohm
