Answer:
The porter charges Rs 300 at this rate.
Step-by-step explanation:
We solve this question by proportions, using rule of three.
75 Rs - 4 km - 50 kg
x Rs - 10 km - 80 kg
Relationship between the variables:
As the distance, or the weight increase, the rate will increase. This means that:
[tex]\frac{75}{x} = \frac{4*50}{10*80}[/tex]
[tex]\frac{75}{x} = \frac{200}{800}[/tex]
[tex]\frac{75}{x} = \frac{2}{8}[/tex]
[tex]x = \frac{75*8}{2} = 75*4 = 300[/tex]
The porter charges Rs 300 at this rate.
