this is a very easy and rather 1min question. I am new to the gmat prep so since you are expert, I wanna confirm if this is the gmat 700 level as far as algebra is concerned? (only talking about algebra here). Thanks
I solved this question in a different way and got the same answer. I took LCD of 3 and 5, because both $3 and $5 certificates need to be there in all the different combinations. I divided 93 by the LCD of 3 and 5 ,i.e., by 15. The quotient is 6, which is the answer. Was my approach right?
Great explanation Sir, I am going through each and every video of yours. For this problem if we could have done m = 31 - 5*n/3 and start with n = 3 we could reach max 18 for n yielding 6 results. Would that be a faster way to solve this ? Thank you again for a great question and explanation.
Note, the average time per question is 2 minutes. That means there are questions that are easy and require less than a minute and those that are likely to take 3 or more minutes. The key lies in knowing this distinction. Understanding the core idea (not just the formula) and solving adequate questions will build this judgement. Best wishes
The question says that "m and n are natural numbers". Natural numbers are only positive integers. Since 0 is neither positive nor negative, it does not count as a natural number.
Wonderful question and Brilliant explanation
Glad it was helpful! Best wishes for your prep!

I solved it through options, is it the right way to solve it quicker?
And we are supposed to solve this types of questions in 2 mins in exam....😵💫, what where they thinking while setting up this exam 🤧

Why can’t m take the value of 0 ?
The question says that "m and n are natural numbers". Natural numbers are only positive integers. Since 0 is neither positive nor negative, it does not count as a natural number.
