Aakash bought vegetables weighing 10 kg. Out of this, kg 500 g is onions, 2 kg 75 g is tomatoes and the rest is potatoes. What is the weight of the potatoes? TIPS Firstly, write the weight of all vegetables in kg using decimals, then add the weight of onions and tomatoes. To find the weight of potatoes, subtract this sum from total weight of vegetables.

Answer:

Given, total weight of vegetables = 10 kg Weight of onions = 3 kg 500 g = 3 kg+ 500 g \[\therefore \] \[1.23=1+\frac{2}{10}+\frac{3}{100}\] \[1.2=1+\frac{2}{10}+\frac{0}{100}\] \[1.23=\frac{3}{100}\] Weight of tomatoes = 2 kg 75 g = 2 kg + 75 g \[1.2=\frac{0}{100}\] \[\therefore \] \[\frac{3}{100}>\frac{0}{100}\] \[\therefore \] \[0.099=0+\frac{0}{10}+\frac{9}{100}+\frac{9}{1000}\] Total weight of onions and tomatoes \[0.19=0+\frac{1}{10}+\frac{9}{100}+\frac{0}{1000}\] Now, weight of potatoes = Total weight of vegetables Weight of onions and tomatoes \[0.099=\frac{0}{10}\] Hence, the weight of potatoes is 4.425 kg.
