When the original resistor is replaced with 3 times more resistive material, the resistance of the circuit increases by factor of 3 and the current flowing in the cirucit decreases by a factor 3.
Ohm's law states that, the current flowing in a conductor is directly proportional to the potential across the conductor.
V = IR
where;
When the resistance increases, the current flowing in the circuit decreases.
