I'm asked by my University Professor, Mandy, to come and see her in her office after class. "Somethin' wrong?" I keep thinking when I head to her office.
"You are elected to be our Math club's consultant and I can see why. However," as Mandy continues, "I will have you solve this question. If you fail to do so, I'll find somebody to take your place."
"Fair enough." I think.
And here's the question: e + f + 20 = 2 c + d + 88 = 5 c + d + e + f = ?
Before I could write down -101 as the answer, Mandy mentioned the answer is not -101!
As I struggle, another student who passed by managed to see the question and said "It is too easy"
"Correct." said Mandy and the student became the Club's consultant instead.
What is the correct answer and, what happened?
Also, could you find all the hidden references in the question?
EDIT: I have made a mistake on the question posted and it's been edited. Unsure if it violate the rule I will go ahead and accept the correct answer
