Three friends start a food stall with ₹12,000, ₹18,000 and ₹30,000 for the same period. They make a profit of ₹9,000. What is the smallest share?

Explanation

1. 01

   Capital ratio = $12{,}000 : 18{,}000 : 30{,}000 = 2 : 3 : 5$, a total of 10 parts.

2. 02

   Smallest share = ₹9,000 × $2/10$ = ₹1,800.
