Question. 108

Alok purchased 1 kg 200 g potatoes, 250 g dhania, 5 kg 300 g onion, 500 g palak and 2 kg 600 g tomatoes. Find the total weight of his purchases in kilograms.

Answer:

\(9.85\,\text{kg}\)

Detailed Answer with Explanation:

Idea to remember: (1000, ext{g} = 1, ext{kg}).

Convert each item to kilograms

Potatoes: (1, ext{kg},200, ext{g} = 1, ext{kg} + rac{200}{1000}, ext{kg} = 1 + 0.2 = 1.2, ext{kg})

Dhania: (250, ext{g} = rac{250}{1000}, ext{kg} = 0.25, ext{kg})

Onion: (5, ext{kg},300, ext{g} = 5, ext{kg} + rac{300}{1000}, ext{kg} = 5 + 0.3 = 5.3, ext{kg})

Palak: (500, ext{g} = rac{500}{1000}, ext{kg} = 0.5, ext{kg})

Tomatoes: (2, ext{kg},600, ext{g} = 2, ext{kg} + rac{600}{1000}, ext{kg} = 2 + 0.6 = 2.6, ext{kg})

Add them step by step

(1.2 + 0.25 = 1.45)

(1.45 + 5.3 = 6.75)

(6.75 + 0.5 = 7.25)

(7.25 + 2.6 = 9.85)

Total weight: (oxed{9.85, ext{kg}})
