Question 391734


given:

12 quintal luggage:18 km

8 quintal: 20 km


Price should go up with more pieces of luggage (directly proportional) and the fraction or ratio is
{{{(12/8)}}}

Price should go up with increased distance also directly proportional and the fraction (ratio) is
{{{(20/18)}}}

and then 

{{{ (20/x)=(12/8)*(20/18) }}} and {{{x = 12}}}

so logically less luggage and less distance cost less to move
