Question

You decide to buy some stocks for a certain price and then sell them at another price. Write a program that determines whether or not the transaction was profitable. Here are the details: • Take three separate inputs: the number of shares, the purchase price of the stocks, and the sale price, in that order. • You purchase the number of stocks determined by the input. • When you purchase the stocks, you pay the price determined by the input. • You pay your stockbroker a commission of 3 percent on the amount paid for the stocks. • Later, you sell the all of the stocks for the price determined by the input. • You pay your stockbroker another commission of 3 percent on the amount you received for the stock. Your program should calculate your net gain or loss during this transaction and print it in the following format: If your transaction was profitable (or if there was a net gain/loss of 0) print: "After the transaction, you made 300 dollars." (If, for example, you gained 300 dollars during the transaction.) If your transaction was not profitable, print: "After the transaction, you lost 300 dollars." (If, for example, you lost 300 dollars during the transaction.) Use string formatting.

Answer 1

Answer:

#here is code in python.

#read number of shares

num_share = int(input("Enter number of shares:"))

#read purchase price

buy_p = float(input("Enter purchase price:"))

#read sell price

sell_p = float(input("Enter sale price:"))

#total buying cost

buy_cost=buy_p*1.03*num_share

#total selling cost

sell_cost=sell_p*0.97*num_share

#if net profit

if(sell_cost>buy_cost):

   print("After the transaction, you made " +str(sell_cost-buy_cost)+ " dollars.")

#if net loss

else:

   print("After the transaction, you lost " +str(buy_cost-sell_cost)+ " dollars.")

Explanation:

Read the total number of shares from user.Then read buying price of a share and selling price of a share.Then calculate total buying cost including commission.Calculate total selling cost excluding the commission.If total buying cost is greater than total selling cost the print the profit else print the loss in the transaction.

Output:

Enter number of shares:10

Enter purchase price:10

Enter sale price:10

After the transaction, you lost 6.0 dollars.
