Answer: The investor gained #440 altogether.
Step-by-step explanation: Calculate the total cost of buying the shares.
Calculate the total revenue from selling the shares.
Determine the gain.
Let's break down each step:
Step 1: Calculate the total cost of buying the shares.
The investor bought 10,000 shares at a price of #1.13½ per share.
Total cost of buying = Number of shares × Price per share
Total cost of buying = 10,000 shares × #1.13½ per share
To simplify the calculation, we'll convert #1.13½ to decimal form:
#1.13½ = #1.135
So,
Total cost of buying = 10,000 shares × #1.135 per share
Step 2: Calculate the total revenue from selling the shares.
The investor sold the shares at a price of #1.18½ per share.
Total revenue from selling = Number of shares × Price per share
Total revenue from selling = 10,000 shares × #1.18½ per share
To simplify the calculation, we'll convert #1.18½ to decimal form:
#1.18½ = #1.185
So,
Total revenue from selling = 10,000 shares × #1.185 per share
Step 3: Determine the gain.
The cost of buying and selling the shares amounted to #1060.
Gain = Total revenue from selling - Total cost of buying - Cost of buying and selling
Now, let's perform the calculations:
Total cost of buying = 10,000 shares × #1.135 per share
= 10,000 × 1.135
≈ #11,350
Total revenue from selling = 10,000 shares × #1.185 per share
= 10,000 × 1.185
≈ #11,850
Gain = Total revenue from selling - Total cost of buying - Cost of buying and selling
= #11,850 - #11,350 - #1060
= #440
