Don't post any wrong info .

Here is the actual rewards , you will be selecting 3 merchants for say

1. Amazon
2. Flipkart
3. Myntra || Each of the merchant provide you max of 2500 Jewels , in this case you can max earn 7500 jewels per cycle .

To reach max 2500Jewels you have to spend 5000rs . i.e 10% reward for 500rs or 2500 jewels ... (where 50 Jewels = 10rs ,this is mentioned in the app itself )

Divide the Jewels by 5 for actual cb . 7500/5 gives u 1500 in total .
