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:

Firstly, we convert all the weight in the same unit i.e. gram into kilogram by divide 1000 and then find the total weight. Given, weight of potatoes = 1 kg 200 g  = 1 kg + 200 g                         \[1\,\,kg+\frac{200}{1000}kg\]             \[1\,\,kg+0.200\,\,kg\]                                                                                                                              \[=1.200\,\,kg\]            \[\left[ \because \,1\,g=\frac{1}{100}kg \right]\] Weight of dhania \[=250\,g=\frac{250}{1000}kg\]                         \[0.250\,\,kg\] Weight of onion \[=5\text{ }kg\text{ }300\text{ }g=5\text{ }kg+300\text{ }g\]                         \[=5\,\,kg+\frac{300}{1000}kg\]                         \[=5\,\,kg+0.300\,kg=5.300\,kg\] Weight of palak \[=500\,\,g=\frac{500}{1000}\,\,kg\]                         \[=0.500\,\,kg\] Weight of tomatoes \[=2\,\,kg\,\,600\,\,g=2\,\,kg+600\,\,g\] \[=2\,\,kg+\frac{600}{1000}kg\]                                                                                                 \[\left[ \because 1\,g=\frac{1}{1000}kg \right]\] \[=2\,\,kg+0.600\,\,kg=2.600\,\,kg\]                                                                                     \[\therefore \] Total weight of his purchases in kilograms = 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 = 9.850 kg Hence/ the total weight is 9.850 kg.
