Preeti, Anu and Aarti entered into a business. Preeti invested Rs 2500 for some months, Anu invested Rs 3000 for 2 more months than Preeti and Aarti invested Rs 3500 for 3 months less than Anu. If Anu got Rs 8400, out of a total profit of Rs 19,000, then Aarti invested her money for how many months?

3 months

5 months

4 months

6 months

Explanation:

Solution:
Preeti : Anu : Aarti
25000*x : 3000*(x+2) : 3500*(x-1)
5x : 6(x+2) : 7(x-1)
So (6x+12)/(5x + 6x+12 + 7x-7) * 19000 = 8400
Solve, x = 5
So Aarti invested money for 4 months
