Question

Question 108.
Alik purchased 1 kg 200 g potatoes, 250 g dhania, 5 kg 300g 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 + $\frac{200}{1000}kg$
= 1 kg + 0.200 kg $\left[\begin{array}{c}\because 1g=\frac{1}{1000}kg\end{array}\right]$
= 1.200 kg
Weight of dhania = 250 g = $\frac{250}{1000}$kg = 0.250 kg
Weight of onion = 5 kg 300 g = 5 kg + 300 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 k g + $\frac{600}{1000}$ kg $\left[\begin{array}{c}\because 1g=\frac{1}{1000}kg\end{array}\right]$
= 2 kg + 0.600 kg = 2.600 kg
$\therefore$ 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 of his purchases is 9.850 kg.
