effective resistance in series is greater than the greatest value of resistance given
effective resistance in series is equal to the sum of all individual resistances
R = R1 +R2 + R3
25 + 50 + 75
=150 ohm
-----------------------------------------------------------------------
effective resistance of the combination of the three resistors = 150 ohm
