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.

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

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).

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.

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.

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

Please tell me about it shortly.

If differences between the numerator and denominator is very low it means it having the high value of that fraction. In this 1/3, 1/5, 6/7 only 6/7 having less difference so series starts from here.

In option D only numerator are in descending order not in other easy and quick method.
