Cant i be solved like this?

as y=5z therefore y/z=5/1

i.e. y = 5k and z=1k

therefore x+y :x+z = 3+5k/x+k

now, substitute values in k =1,2,3,... to get some values and match it with options available?

Please format the question in the proper way: using the right title, and using the expression. They are just above the corpus of the message.

Post the question in the right sub-forum.

Thank you

the answer should match for all values of k not just for some. This question doesn't make sense.

What is the source?
