Hello J. A friend of mine suggested your blog and I must say that it has literally taken my learning curve to a whole different level altogether, so thank you for that firstly.

And since the post is Singles, with no specific topic. Could you please do one on Averages as well, not the basic but nasty problems they bombard us with in AIMCATs.

Problems of this type: There are five positive integers. When any four of these integers are considered and their average is added to the fifth integer, we get the following numbers: 41, 44, 50, 56 and 65. Which of the following gives the value of one of these five integers? Options 28, 44, 36, 18.

• Should be doing something similar in a singles post early next month. The more standard version, where they are just weighing 2 or 3 at a time, but from that you can extrapolate how to approach this ðŸ™‚

Yes, that would be awesome!! It’s all about getting hold on fundamentals, and from there on application of that knowledge. Eagerly awaiting your approach for these ghoulish questions, as I find taking numbers as a, b, c, d and e and then forming 5 equations and deriving values, totally non-feasible for a 2 minute limit question.

• Hint though: I suspect that without writing equations we can conclude that the 5 given numbers add up to twice the 5 original numbers. (Average means 4 taken 4 times + the number itself once for each of the 5 original numbers)

Yes. You are absolutely right. Wow, how did you come up with it like that?

• Because I have been thinking about a similar problem very recently for the blog ðŸ™‚ Helps if it is somewhat top of mind.

Hi, Sir
is there any link where all Singles post are there together? like in the order of 1,2,3….and so on?

• They’re all on the “paperless” tag, along with other posts/questions with unconventional (and short) solutions ðŸ™‚
