If Tk. 45,000 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 purchased?

Correct Answer: Tk. 75
Total investment = 45000 + 30000 = 75000 Number of shares bought by at 90 TK rate = 45000/90 = 500 Number of shares bought at 60 TK rate = 30000/60 = 500 Total number of shares bought = 500 + 500 = 1000 Average share price = 75000/1000 = 75 TK
