Explanation

The typical way to do this problem would be to assign variables and set up equations, using x to represent the number of classes Randolf took, 12x to represent the amount he paid, and 45x to represent the number of minutes he spent.

A quicker way might be to notice that with every class Randolf takes, the difference between the number of minutes he spends and the amount he pays increases by 33. If Randolf takes 1 class, then the number of minutes he spends is 33 greater than the number of dollars he pays. If he takes 2 classes, the number of minutes is 66 greater than the number of dollars, and so on. Since 132 = 4 × 33, Randolf must have taken 4 classes.

Hence option B is correct!

We can let n = the number of classes Randolf attended. Thus, the number of minutes he spent is 45n, and the number of dollars he paid is 12n. We can create the equation:

45n = 12n + 132

33n = 132

n = 4

Answer: B

Hi @JeffTargetTestPrep,

That was a really nice explanation. Can you please tell me where i can find similar questions to practice besides the 5lb book. I'd be grateful.

Thanks,

Hi,

Above in the first post all you need is to hit the tag word problem between the level of difficulty and the source of the question.

Hope this helps.

Regards

Thank you carcass. Theres another question actually two.

1. Is it OK to practice "word problems" from the "problem solving" section of gmat og's?
2. How do i improve my equation making skills for these wordy/convoluted questions as jeff has done.

Thanks,
Asfand.

1) yes, of course. You must. At the end of the day every kind of problem is a "word problem".

2) The best way to improve your "word problem" skills is to work specifically on a few concepts related to this category. However, you will improve when your math skills as a whole will improve because will become natural to understand the problem and translate it as a consequence of your math skills.

Nonetheless, you could read this post https://gmatclub.com/forum/word-problem ... 87346.html or use this book https://www.amazon.com/Word-Problems-Ma ... 1937707903

Ask if you do need something else.

Regards
