D8: GAT - let's attempt a few questions

[vaguebrownfox01]

• two candidates election; 20% invalid votes
• calculate the percentage error: 3/5 5/3 | important error of what? (16/15) / (5/3) * 100
• tailors: x paid 120% more; ease calculation by using 100

[!NOTE]

• don't overload the mind with all the details from the question
• separate what is given and what to find out
• practice to understand the question in one shot
