I will describe here about the application Google Opinion rewards. Its an application which asks you some questions. You should select your opinion. I am using this application for the last 8 months. During this time period I have earned only 64Rs .
This money cannot be transferred to our bank account. It can only be used in Google play store. If we dont use this money within one year then this money will be expired.
In a week there will be only 1 survey given to you. By completing this I got maximum 9Rs in a week. Some weeks I got only 3Rs or 7Rs.
Some of the questions asked to me is as follows:
How many hours do you spend for sleep.
How often do you use taxi services.
How many times do you use social medias.
