600+ posts 200+ kudos..and still not credible enough for you... Huh.. WTF..

Let me show one calculation to you..

1/6= 0.1666666...
Or
1-1/6= 1-0.166666666..

Or 5/6= 0.83333333..

Let me see, how do you better this approach?

I guess he/she was looking for the Official explanation since the question is from Veritas....

Please note that OA and options are NOT available in the source. Please suggest the best approach to solve this in the least possible time.


5/6 and 0.8333 respectively..

The best approach is to know the pattern of fractions... For example, any fraction, N/3 would be of form X.3333333 or a multiple of it (Y.6666666) or integer
Or, any factor, N/4 would be of form X.25 or a multiple (Y.50, Z.75) or integer
And so on...

For the given question
It comes down to:
5/6 * 1/7 * 7/8 * 8/9 * 9= 5/6 or 0.83333


Dude- it's not that I'm not convinced with your approach..It's great and shows the right one i think but as Macfauz rightly mentioned i was looking for official explanation from Veritas (as they're in this business and always strive to improvise things!)

@Macfauz - It's 'he' :)

Recognizing patterns in decimals was a long pending issue with me. So after seeing this question I decided to prepare following chart.
Following chart can help you to recognize patterns in decimal places (also applicable for percentage) and you can pic appropriate fraction using it.

I hope this chart will save your effort and time, take a print and paste it on your ceiling :)

Now back to the question:

0.8333 is 5/6,
0.143 is 1/7,
0.875 is 7/8,
0.889 is 8/9

Now it is easy to solve this question.

Mind that we do not have the answer options for this one. It would have helped to find the answer had we had the answer options.
