The ratio of the sales of three types of car is 4 to 5 to 7. What are their sales?
1). The sales of r are between 10 and 20
2). The sales of c are less than 10
Can you please check the source and edit the post ? The question looks incomplete to me.
The question should specify the ratio in terms of r and c i,e. r:c:x = 4:5:7 etc. which isn't so in this case. and also can you please quote the source of the question.
word problem
