If Tk. 4500 was invested in a share when the price per share was Tk. 90 and Tk. 30,000 was invested when the price per share was Tk. 60, what was the average price per share prchased?

Correct Answer: Tk. 80
Total number of share = 4500/90 + 30000/60 = 50 + 500 = 550 Average price per share = ( 4, 500 + 30, 000)/550 = Tk.62.73
