Question

A goat and a cow together weigh 190 kg 640 g. The weight of the goat is 59 kg 720 g. Find the weight of the cow

Answer 1

Answer: 130 kg 920 g

Explanation:

Given

The weight of the goat is 59 kg 720 g

The combined weight of goat and cow is 190 kg 640 g

Suppose, the weight of the cow is x kg

We know, 1 kg=1000 g

Converting weight into kg

Goat weight

`=59+0.720\\=59.720\ kg`

Total weight

`=190+0.640\\=190.640\ kg`

Then, the cow weight is given by

`\Rightarrow 190.640-59.720\\\Rightarrow 130.920\ kg\ \text{or}\ 130\ kg\ 920\ g`
