Multiple 404 errors for single post links

Hi,

I have administrating a technology site Techracket.com. from the last week, when I looked into the search console I found that there was multiple 404 error for single posts like below.

“http://www.techracket.com/tubemate-2-2-6-free-tubemate-app-video-downloading-app/&sa=U&ved=0CDcQFjAFahUKEwi0rfGegd3GAhXhrKYKHYIFAOU&usg=AFQjCNFlpGlHIOcJRzY0zTYLZEez4l3T1w”

till now the site has more than 100 errors. I cannot able to predict why there was multiple errors for a single page. please help me to take over this issue.
