Answer:
7.5 kg
Explanation:
We are given that

Length of plank, l=3 m
Distance of fulcrum from one end of the plank=1 m

We have to find the mass must be on the other end if the plank remains balanced.
Let m be the mass must be on the other end if the plank remains balanced.
In balance condition






Hence, mass 7.5 kg must be on the other end if the plank remains balanced.
