How can I install i work in ipad ? - Apple iPad (16 GB) WiFi Tablet PC

Incorrect port part, Wrong polarity for wires connected to the port or poor connection of wires to the port.

If you're not going to jailbreak the iPad don't bother. If it's already "broke" then installation is not an issue.

if you have laptop/desktop computer you can sync the iPad with iTunes and download iOS 8.1.2 there:
Upgrading iPad to iOS 8: Through iTunes 1. Backup your iPad
Open iTunes. Select your iPad in iTunes and click Back Up Now.
2. Restart your iPad and your Computer
3. Download and Install the Update
Go to iTunes -> Select iPad -> Check for Update -> Click Download and Update

Whichever method you choose, the process will take quite some time to work depending on how much free storage you have on your iPad, your internet connection, and how Apple's servers are doing with upgrades. Occasionally, Apple will either not let you download the upgrade or it will fail. For iOS 8, you must have an iPad 3 or newer. This does not work with the original iPad - if something goes wrong, restart your device, and try again.

You're not officially supported.
Install the app. Input your cell phone number in the app on the ipad. When you get the activation code on the cell phone input it to viber on the ipad and it should work over Wifi from there. Note that anyone who uses viber to try and reach your cell phone is going to get your ipad instead.

The google playstore doesn't work on an iPAD. It's for Android only.

Try to update it (if possible)

Yes, jailbreaking your iPad is the fast solution, and if you prefer a simple yet fast fix to jailbreak your iOS device. You can take a try of AutomaticiPhoneUnlockers, it can help jailbreak or unlock as many iPad, iPhones, iPod Touches as you like. After that you can install any apps on the device.

You can install any of the iWork apps on your iPad, but you need to buy and install the individually. Just search 'Numbers', 'Pages', 'Keynote' in the iPad App Store and you'll be able to get them.
You have to buy them even if you've already bought iWork for desktop, but they don't cost very much and they're absolutely worth it. They work really well and barely ever crash.
Hope that helped!
