Question

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 1

Firstly, we convert all the weight in the same unit,

i.e. gram into kilogram and then find the total weight.

Given, weight of potatoes = 1 kg + 200 g

= 1 kg + 200 g = 1 kg + `200/1000` kg

= 1 kg + 0.200 kg   .....`[because 1 g = 1/1000  kg]`

= 1.200 kg

Weight of dhania = 250 g = `250/1000` kg = 0.250 kg

Weight of onion = 5 kg 300 g = 5 kg + 300 g

= 5 kg + `300/1000` kg = 5 kg + 0.300 kg

= 5.300 kg

Weight of palak = 500 g = `500/1000` kg = 0.500 kg

Weight of tomatoes = 2 kg 600 g = 2 kg + 600 g

= 2 kg + `600/1000` kg    .....`[because 1 g = 1/1000  kg]`

= 2 kg + 0.600 kg = 2.600 kg

∴ Total weight of his purchases in kg = Weight of potatoes + Weight of dhania + Weight of onion + Weight of palak + Weight of tomatoes

= 1.200 kg + 0.250 kg + 5.300 kg + 0.500 kg + 2.600 kg

= [1.200 + 0.250 + 5.300 + 0.500 + 2.600] kg = 9.850 kg

Hence, the total weight is 9.850 kg.
