In our college mess, Parle-G biscuits are a daily snack. Exploring the biscuit market, I found Parle-G holds 13% of the biscuit market, worth $6B in FY22. With $780M in sales, Parle-G contributes significantly to Parle's $2B revenue, despite offering 200 products. This illustrates the 80:20 rule—20% of products generate 80% of revenue—similar to Amazon's reliance on AWS.
