Elon and Alex started work together with investments of ₹2400 and ₹3200 respectively. After one year, Mike also joined with an investment of ₹3500. If after two years they earned a profit of ₹5880, then find Elon’s share of the profit.
- ₹2520
- ₹1920
- ₹2240
- ₹1800
Correct answer: ₹1920
Solution
Elon and Alex invest from the start, while Mike joins after one year. So their capital-time ratios are Elon: $2400\times 2$, Alex: $3200\times 2$, Mike: $3500\times 1$. This gives the ratio $4800:6400:3500 = 48:64:35$, and Elon’s share is $5880\times\frac{48}{147}=₹1920$.
