$\frac{20}{5} = \frac{30}{x} \\ 20x = 30 \times 5 \\ 20x = 150 \\ x = \frac{150}{20} \\ x = \frac{15}{2} \\ x = 7.5$

$30 \: apple \: = 7.5kg$

Answer 2

According to the information provided in the preceding question,

The supplied value is as follows:

The weight of 20 apples is 5kg  

We have to find the weight of 30 apples

Here we have to first find the weight of one apple.

Thus, the weight of one apple is as follow,

$=\frac{5}{20} \\=0.25kg$

Therefore the weight of 30 apples is,

$=30\times 0.25\\=7.5kg$

Hence the weight of 30 apples is 7.5kg
