The fraction whose numerator after cross multiplication gives the greater value is greater.

Here take the 1st two 6/7 and 5/6
6*6>5*7.

From given options option D only satisfy this...So ans is D.

Consider the options A, B, C.
First 2 numbers are 1/3 and 2/5.

Multiply first with 5 and second with 3 then it becomes,
5/15 and 6/15:::: it is ascending order.

Hence option D is the correct answer.

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.

Make denominator same;

Option D.

= 6*30/7*30, 5*35/6*35, 4*42/5*42, 3*30/7*30, 2*42/5*42, 1*70/3*70.
= 180/210 ,175/210 ,168/210 ,90/210 ,84/210 ,70/210.
Arrange the numerator in descending order.

Find the LCM of denominators. Then we get 210. Multiply it with current value (eg: 210*1/3 = 70) and find all values. Then you can find which one is the correct answer. Here the answer is option D.

Product of 2nd number denominator with 1st number numerator is more than pr of 1st number deno with 2nd number numo then 1st number is greater ,

Here in d option 36>35(6*6 > 7*5)

By carefully watching this particular problem, we can observe that the option A,B & C numerators are in ascending order whereas the option D numerator are given in descending order.

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

Tell me about the trick in this problem.

I know to multiply with hcf in the denominator and finding decending order but I think their is trick for it.

Please tell me the trick.

Dipti said:   2 decades ago
First take LCM of denominators.

Here it s 210.

Then multiply with multiplier that makes denominators 210.

By doing this.

First becomes 70/210, 84/210 and soon.

Hence ans D.
