Profits : Class Eight Mathematics: Chapter Two : Example 6

Image
Example 6. Profit-principal of some principal becomes Tk. 5500 in 3 years and profit is 8/3 of the principal. What are the principal and rate of profit?

Solution:
We know, principal + profit = profit-principal


                                                ∴ Profit = profit-principal principal
                                              = Tk. (5500 4000)
                                              = Tk. 1500

                             Again, we know, I = Prn
