Answer:
the cost of 250gms of sugar is Rs.4.5.

We know that 1kg=1000gm.
It is given that the cost of 1kg sugar is Rs.18 which means that the cost of 1000g sugar is Rs.18 then cost of one gram sugar will be:
1000
18
=0.018
Therefore, 1gm sugar costs Rs.0.018.
Now, the cost of 250gms of sugar will be as follows:
Cost×number of grams=0.018×250=4.5
