Question

A certain animal in the zoo has consumed 39kg of food in six days, if it continues to eat at the same rate, in how many more days will its total consumption be 104?

Answer 1

Answer:

39 kg = 6days

or, 1 kg = 6/39 days

hence,

104 kg = 6/39 *104 = 16 days

SO, more days needed = 16-6 = 10 days

Answer 2

Given,

The amount of food consumed in six days$\[ = 39{\rm{kg}}\]$

Solution,

The amount of food consumed per day$\[ = \frac{{6}}{39}{\rm{kg}}\]$

The number of days in which $\[104{\rm{kg}}\]$ is consumed

$\[\begin{array}{l} = 104 \times \frac{6}{{39}}\\ = 16\end{array}\]$

Therefore, the number of days are

$\[\begin{array}{l} = 16 - 6\\ = 10\end{array}\]$

Hence, the number of days are $\[10\]$ days.
