Q500 by XOLO
It may be more than 7K but with little bargaining you may get it i 7K in open market.
Q500 - 1GB RAM only Android Phone in your budget.
All others are 512 GB RAM Android Phones.
Iris 402 has 256 MB RAM only, hence not good choice in Android in your budget.
increase budget slightly and get Nokia Lumia 520. worth it than going for local brands. Else check Gionee P3 @ 7.1k. XOLO A500S is also worth checking.
1GB ram and android under 7k: IBall Andi 4.5z
Q500 has ancient android & really weak chipset.

402+ has 512MB ram and more internal memory.
No disrespect but IBall Andi 4.5z has 512 MB RAM.
Gionee P3 or Nokia X. Never buy asha crap.
