There are many survey sites which give some remuneration for the the time spent for those surveys. The remuneration varies from survey to survey. Some of them do not give cash and only give some coupons or vouchers which can be redeemed at the merchant outlets physically or online.
Some of the popular and reputed sites are ValuedOpinions, iPanelOnline, Cashcrate, The Panel Station, Viewfruit India Panel etc. One can try to register there and see the modalities before going to take up the surveys on a larger scale.
One thing which I want to mention about these sites is they will be checking and rechecking your profile data like age, annual income, gadgets hold, family details etc time to time and if there are variations in your feedback then the survey might be terminated and you lose the chance to participate. So be consistent in your profile and do not answer vaguely. It is very important if you want to take up the surveys for earning some money. Most of these sites will require a Paypal account also.
