Certain PDF files open with scrambled...

[Guest]

I received two brochures from some colleagues but the text and graphics were scrambled - photos were OK. I thought they sent damaged files. I sent them a screen shot of what I saw when I opened them and they in return sent a screen shot of what they saw when they opened the same files. Theirs showed a perfect brochure. I have since opened the same pdf at work and it was fine there too - BUT it opens scrambled on my iphone and iMac desktop.   Why would Apple products not be able to read or display a pdf? I thought a pdf was universal.... Is there a solution to this? I made sure all my software on my macBook pro was updated and still no luck.  Here are the two screen shots - first is how the pdf looks when I see it. Second one is how everyone else sees it..... Thank you for any suggestions to this problem. This is for a very important cause -my brother's orphanage- so I hope it can be resolved soon! Thank you,Bob
