=> cost of 1 g apples = ₹40/500

=> cost of 300 g apples = ₹40×300/500

= ₹12000/500

= ₹120/5

= ₹24

Hence cost of 300 grams of apples = ₹24

Answer 2

$\sf{\huge{\underline{\orange{Given :-}}}}$

• The cost of half kg of apples is Rs 40.

$\sf{\huge{\underline{To\:Find :-}}}$

• The cost of 300 grams of apples.

$\sf{\huge{\underline{\green{Answer :-}}}}$

We know,

1 kg = 1000 g

½ kg = 1000/2 = 500 g

According to the question,

Using unitary method here.

The cost of half kg of apples is Rs 40.

500 g of apples cost = Rs 40.

1 g of apple cost = 40/ 500

the cost of 300 grams of apples = 40/500 × 300

➝ 40/5 × 3

➝ 8 × 3

➝ 24

The cost of 300 grams of apples is Rs. 24.
