Equate the denominators using the LCM of the denominators as follows:

LCM of 7, 11, 15, 17, and 9 = 7 x 11 x 9 x 5 x 17 = 58905

Hence, can be written as =

can be written as =

can be written as =

can be written as =

can be written as =

As can be seen,

< < < <

Hence, < < < <

Since, option ‘1’ gives this arrangement, it is the correct answer.

**(Ans: 1)**

*Estimated Time to arrive at the answer = 200 seconds.*

**Using Technique**

We already know the value of the reciprocals of 7, 11, 15, 17 and 9 as:

= 0.1482…

= 0.09090…

= 0.0666…

= 0.0588…

= 0.1111…

From above it is clear that,

< < < <

**(Ans: 1)**

*Estimated Time to arrive at the answer = 60 seconds.*
