I vividly remember the time when I took the UP MBA Proficiency Exam. I was jittery back then, but I was feeling confident that I will somehow pass the UP MBA Proficiency Exam. I didn’t really take too much time to study algebra in detail, as I knew I’ve aced the UP MBA GPAT. Bulk of UP MBA GPA quantitative exam are algebra questions. Plus, I never had an UP MBA Reviewer for the Proficiency Exam, hence, relying on what I just remember.
Then ….. I WAS WRONG! I eventually flunked the algebra part of the UP MBA Proficiency Exam, in which I needed to retake after the UP MBA workshops.
I somehow remember one question from the Algebra part of the proficiency exam – the Mensa Question. This could form part of their UP MBA reviewer. Honestly, it gave me headaches when I first read the question. It said, quoted in parenthesis, in the first part of the question that “the question is very easy but you will need your imagination and creativity to answer this question correctly”. I did use my imagination on my first try, but in the end, my answer is incorrect (better imagination maybe?). When the question was discussed in the UP MBA Workshop, I felt so clueless that the question is so easy to answer.
Try it yourself. maybe this can help you and be an important part of your UP MBA Reviewer! A similar question, though not 100% identical to the UP MBA Proficiency Exam Questions, and its solution is written below. Just one suggestion, PLEASE read the problem first, try to answer it then compare your answers to the solutions.
The Mensa toy store is having a special sale of used toys. Everybody is confused about the prices. At this sale, a TRUCK costs $220, a CART costs $170, and a BALL costs $170. How much would a SHOVEL (the kind a child might use at the beach) cost under the Mensa system of setting prices? What would a TRAIN cost? What would a TEDDY BEAR cost?
- This is a system of equations problem. In this case, we need to set-up at least 2 equations. In order to do that, we need to use our imagination and creativity.
- Your creativity will be needed in the assumption of variables. Now, let us define two unknowns: one for consonants and one for vowels, or C and V variables respectively.
- Our system of equations is:
- 4C + 1V = 220 (Truck)
- 3C + 1V = 170 (Ball)
- 3C + 1V = 170 (Cart)
- Now, we have 2 equations with 2 unknowns! ( #2 & #3 are the same) We can now solve for the value of a consonant and a vowel (variables C and V).
- Using algebra, we can solve for the variable V by simplifying equation #2. The resulting equation is: V = -3C + 170
- We then substitute the resulting value of V to the variable V found in equation #1. The equation looks like:
4C + 1(-3C + 170) = 220 >>> 4C – 3C = 220 – 170 >>> C = 50
- We now have the value for C, which is $50. We now substitute the value of C to equation #2 to determine the value of V.
3 (50) + 1V = 170 >>> 150 + V = 170 >>> V = 170 – 150 >>> V = 20
- Given that we know the value for each variable, we can now answer the main question of the problem, which to know the prices of a TRUCK and a TEDDY BEAR.
- By direct substitution, the prices, or the answers to our Mensa Problem, are:
TRAIN = 3C + 2V >>> 3 (50) + 2 (20) >>> 150 + 40 >>> TRUCK = $190.00
TEDDY BEAR = 6C + 3V >>> 6 (50) + 3 (20) >>> 300 + 60 >>> TEDDY BEAR = $360.00
Looking back, it was a truly a great learning experience! If only I encountered it in an UP MBA Reviewer. Though I seemed to look crap in answering trick questions like those back then, it further helped me in dissecting and analyzing trick problems better; more so when I was accepted in the UP MBA Program. The UP MBA Proficiency Exam also helped me gauge what subjects I need to sharpen my brain-tools on, in preparation to the grueling task of finishing the UP MBA program.
