O None of these​

Answer 1

$\bf{ \purple{ \underline{Solution :-}}}$

⟹ 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:

$⟹\bf{ \frac{18}{1000} = 0.018}$

⟹ Therefore, 1gm sugar costs Rs.0.018.

⟹ Now, the cost of 500gms of sugar will be as follows:

⟹ Cost × number of grams = 0.018 × 500= 9

⟹ Hence, the cost of 500gms of sugar is ↷

$\bf{ \boxed{ \purple{Rs \: 9}}}★$

▪︎ Thus, the (A) option is correct ✅
