@Umesh.
Your trick is not applicable for all types of questions.
It will work only when difference between the given numerator is equal.

Easy trick for solving this type of question 1st take difference of numerator and denominator and arrange them according to there acceding and descending order and respective fraction is answer of question if deference is common between 2 fraction then select greater base between them is higher value fraction.

It is very easy. Among all option check out the last and first number you will get answer.

6/7*5/6 cross multiplication.
36, 35 (6/7 = 36, 5/6 = 35).
6/7 > 5/6.
36, 35 (6/7 = 36, 5/6 = 35).
6/7 > 5/6.

Check this technique:
In starting it may be consume some time but after practice we will solve in second.
6/7, 5/6, 4/5, 3/7, , 2/5, 1/7.
Check difference between numerator and denominator and then divide numerator with difference.
6-7 = 1.
6/1 = 6.
5-6 = 1.
5/1 = 5.
Don't confuse with numerator greater or smaller.
4-5 = 1.
4/1 = 4.
3-7 = 4.
3/4 = 0.7.
2-5 = 3.
2/3 = 0.6.
1-7 = 6.
1/6 = 0.1.

Observe the all options in numerators and denominators.
If numerators increases value increases. But they are asking for decreasing order.
So denominator decreases the value decreases.
So there is only one option 6, 5, 4, 3, 2, 1.
So option: D.

I did it by seeing just observe any numbers with same denominators like I supposed 7 denominator for option A I saw that 3/7 is coming before then 6/7 so option A is not in descending order, like as I tried B & C, lastly I got D which is correct for my consideration.

Let us check option D.
Write 6/7 = 60/7, 5/6 = 50/6, 4/5 = 40/5, and so on it makes easy to calculate. Since we converted them into improper functions.
8.5, 8.2, 8, 4.2, 4, 3.3

For the first three option take the 1st and last digit, then compare the two digit.
For option a), b)and c)
1/3=0.3333 and 6/7=0.8571, now we can see that 1st one is smaller then last one.
So they are not in descending order.
Hence answer is the rest means option D).
