• A. $Rs.9$
• B. $Rs.4.5$
• C. $Rs.8$
• D. $Rs.5.5$

Answer 1

The correct option is B $Rs.4.5$

We know that $1$kg=$1000$gm.

It is given that the cost of $1$kg sugar is Rs.$18$ which means that the cost of $1000$g sugar is Rs.$18$ then cost of one gram sugar will be:

$\frac{18}{1000}=0.018$

Therefore, $1$gm sugar costs Rs.$0.018$.

Now, the cost of $250$gms of sugar will be as follows:

Cost$\times$number of grams$=0.018\times 250=4.5$

Hence, the cost of $250$gms of sugar is Rs.$4.5$.
