Final answer:
To calculate Kiara's percentage of the total profit, we must first compute the total investment each partner has made over two years, and then find Kiara's proportion of the total investments.
Step-by-step explanation:
The question is regarding a partnership and the distribution of profits according to the investments made by different partners over a period of 2 years.
To solve for Kiara's share in the profit, we will have to calculate each partner's total investment over the two years and determine the proportion of Kiara's investment to the combined total.
For Rajeshwari: Initial investment is 10 lakh, which increases by 10 lakh every 4 months. So, over 24 months (2 years), she will increase her investment five times (since 24 months / 4 months = 6 total investments - 1 original).
For Kiara: Initial investment is 20 lakhs, increasing by 20 lakh every 6 months. Over 24 months, Kiara will make three additional investments (24 months / 6 months = 4 total investments - 1 original).
For Nikki: Initial investment is 30 lakhs, and it increases every 9 months. Over 24 months, Nikki will increase her investment two times (since 24 months / 9 months = 2.66, which rounds down to 2 total increases).
For Khushi: Initial investment is 80 lakhs, which reduces by 50% after a year.
After calculating the total investments made by each partner, we will divide Kiara's total investment by the sum of all partners' investments to get her share of the profits, and then convert that into a percentage.
