A starts a business with ₹4000, and B joins the business 4 months later with an investment of ₹5000. After a year, they earn a profit of ₹22000. Find the shares of A and B. A ₹4000 বিনিয়োগ করে একটি ব্যবসা শুরু করে এবং 4 মাস পরে B ₹5000 বিনিয়োগ করে যোগ দেয়। এক বছর পরে, তারা ₹22000 লাভ করে। A এবং B-এর অংশ কত?

A starts the business with ₹4000 and B joins after 4 months with ₹5000. So, A’s investment is for 12 months, and B’s investment is for (12 − 4) = 8 months.

Now, ratio of their investments = (4000 × 12) : (5000 × 8) = 48000 : 40000 = 6 : 5

Total profit = ₹22000 A’s share = (6 / 11) × 22000 = ₹12000 B’s share = (5 / 11) × 22000 = ₹10000

Hence, A and B’s shares are ₹12000 and ₹10000 respectively.
