Average Return Calculation for Stocks
This problem requires calculating the return of a single stock using the concept of average returns.
Calculate Sum of Four Stocks' Returns
Four stocks have an average return of 8%. The total sum of their returns is calculated as:
Sum of 4 stocks = Number of stocks $\times$ Average return
Sum of 4 stocks = $4 \times 8\% = 32\%$
Calculate Sum of Five Stocks' Returns
The overall average return for all five stocks combined is 9%. The total sum of returns for these five stocks is:
Sum of 5 stocks = Number of stocks $\times$ Overall average return
Sum of 5 stocks = $5 \times 9\% = 45\%$
Determine the Fifth Stock's Return
To find the return of the fifth stock, subtract the sum of the returns of the first four stocks from the total sum of returns for all five stocks.
Return of 5th stock = (Sum of 5 stocks) - (Sum of 4 stocks)
Return of 5th stock = $45\% - 32\% = 13\%$
