Answer 1

(i) 1000 grams = 1kg
14400 grams = 14.4 kg
$\frac{1}{0.245} = \frac{14.4}{x} \\ x = 14.4 \times 0.245 \\ x = 3.528$
Ans: 14400 grams of milk contains 3.528 kg of fats.

(ii) 1kg = 1000 grams
10kg = 10000 grams
3kg 500 g = 3500 grams
2kg 75 g = 2075 grams

Total vegetables = onion + tomato + potato
10000 = 3500 + 2075 + potato
10000 = 5575 + potato
potato = 10000 - 5575
potato = 4425

Ans: The weight of potato is 4kg 425 grams.
