Question

five resistance are connected in as shown figure determine the total resistance

Answer 1

7 and 3 are in series.the resistance of 7 and 3 is 10.
now, 10 and 10 are in parallel.now the r is 5.
the three 5 ohm resistors are in series.
therefore the net resistance is 15 ohm

Answer 2

The 3 ohm resistance and 7 ohm resistance in series so net resistance will 10 ohm then this 10 ohm resistor and another 10 ohm resistor in parallel so net resistance will become 5 ohm then another 5 ohm resistor this 5 ohm resistor and 5 ohm resistor are all in series then net resistance will be 15 Ohm .
