You would have answered 48 of 60 questions correct.
To figure out a mathematical problem like this again here is how you set up the equation:
First, you need to know how many you answered correct out of 60. The unknown value is then X.
X /60
Second, you know you achieved a percentage of 80%. This means, in other words, if there were 100 questions you would have answered 80 correctly. (The ratio for percentages is something over 100).
80/100
You now have your equation!!
X/60 = 80/100
Start by multiplying 80 by 60 to isolate the variable (X).
X = 4800/100
Simplify the equation.
X=48
There is your answer!! In order to achieve a score of 80% you would have answered 48 of 60 questions correctly. :-)
20
71% of the questions were answered correctly
45 were correctly answered
100*(21/25) % = 84%
If you answered 27 correctly and 18 incorrectly, you would have answered 60% correctly.

-- Since she answered 86 percent of the questions correctly, she answered the remaining 14 percent of them incorrectly. -- 14% of 100 questions is 14 questions.
