.I will give you a general solution for this kind of problem. Just try to understand that to generalize is better.

Now, solve this: take the three parts of that spring and group them in parallel. If original k = 100 N/m and the sistem is subjected to a force of 1.8 kN, what will be the elongation?
L.E. I will provide another demonstration.
Think this. You have a spring made of three identical springs grouped in series. As you know, the equivalent spring constant can be written:
1/k = 1/k1 + 1/k2 + 1/k3, where k1 = k2 = k3 = k’
So 1/k = 3/k’
Hence k’ = 3k.

Answer:
The answer will be 3k.
Explanation:
In this case each part in series is just similar to the parallel combination of resistors or series combination of capacitors.
