What is Neeta’s share in the profit earned at the end of 2 years in a joint business run by Neeta, Seeta and Geeta ?

I. Neeta invested Rs. 85,000 to start the business.
II. Seeta and Geeta joined Neeta’s business after six months investing amounts in the ratio of 3 : 5 respectively.
III. Totat amount invested by Seeta and Geeta is Rs.2.3 lakhs.

To find the profit earned, we require time period and investment of each person. Thus, all the statements are necessary

From I,II & III : Neeta invested Rs. 85,000 for 24 months while Seeta and Geeta invested for 18 months.

Amount invested by Seeta = $$\frac{3}{8} \times 2.3 = $$ lakhs

= $$Rs. 86,250$$

=> Amount invested by Geeta = $$2,30,000 - 86,250 = Rs. 1,43,750$$

=> Ratio of share in profit of Neeta , Seeta and Geeta

= $$(85,000 \times 24) : (86,250 \times 18) : (1,43,750 \times 18)$$

$$\therefore$$ We can calculate Neeta's share in profit.

Thus, all the statements are necessary.
