Let Anuj do the work in x days.
 So, Bhanu = 3x days, Chandu = 9x days and Dodo = 27x days
Now, using options,
Anuj + Chandu = 1/x + l/9x = 10/9x,
So, they take 9x/10 days
Bhanu + Dodo = l/3x + 1/27x = 10/27x, So, they take 27x/10 days
Now, 1/3 of 27x/ 10 = 9x /10.
 So, Anuj and Chandu is first pair.

Given information:
- Anuj takes a certain number of days to complete a piece of work.
- Bhanu takes three times the number of days as Anuj to complete the work.
- Chandu takes three times the number of days as Bhanu to complete the work.
- Dodo takes three times the number of days as Chandu to complete the work.
- Two pairs of people are formed.

Objective:
To determine which pair belongs to the first pair, which takes one-third the time taken by the second pair to complete the work.

Analysis:
Let's assume that Anuj takes x days to complete the work.
- Bhanu takes three times the number of days as Anuj, which is 3x.
- Chandu takes three times the number of days as Bhanu, which is 3(3x) = 9x.
- Dodo takes three times the number of days as Chandu, which is 3(9x) = 27x.

Determining the time taken by each pair:
First Pair:
- Anuj and Chandu together take x + 9x = 10x days to complete the work.

Second Pair:
- Bhanu and Dodo together take 3x + 27x = 30x days to complete the work.

Comparing the time taken by the two pairs:
The first pair takes one-third the time taken by the second pair to complete the work.
- (10x) = (1/3)(30x)
- 10x = 10x
- The time taken by the two pairs is equal.

Conclusion:
Since the time taken by the two pairs is equal, the first pair consists of Anuj and Chandu. Therefore, option B, "Anuj and Chandu," is the correct answer.
