The human body is made up mostly of water. In fact, about 67% of a person’s total body weight is water. If Jyoti weights 56kg, how much of her weight is water?

1. Break Down the Problem

To find out how much of Jyoti's weight is water, we need to calculate 67% of her total body weight, which is 56 kg.

2. Relevant Concepts

The concept we will use is the percentage calculation: $\text{Water weight} = \text{Total weight} \times \left( \frac{\text{Percentage of water}}{100} \right)$

3. Analysis and Detail

To calculate how much of Jyoti's weight is water, we will perform the following calculation:

1. Take Jyoti's weight: $56 \text{ kg}$
2. Convert the percentage to a decimal: $67\% = 0.67$
3. Multiply Jyoti's weight by the decimal:

$\text{Water weight} = 56 \text{ kg} \times 0.67$

Calculating this gives us:

$\text{Water weight} = 56 \times 0.67 = 37.52 \text{ kg}$

4. Verify and Summarize

The calculation above is straightforward, and we have verified that the multiplication has been done correctly. Jyoti has approximately 37.52 kg of water weight.

Final Answer

Jyoti's weight in water is approximately 37.52 kg.
