Verified Answer
Arun can do a certain work in the same time in which Bipasha and Rahul...
Arun, Bipasha and rahul’s 1 day work = 1/10 + 1/50 = 6/50 = 3/25
Arun’s 1 day work = Bipasha + Rahul ‘s 1 day work
2*(Arun’s 1 day work) = 3/25
Arun’s 1 day work = 3/50
Bipasha’s 1 day work = 1/10 – 3/50 = 2/50 = 1/25

Arun + bipasha=10
rahul. = 50
suppose total work is 50
so, arun bipasha (eff) = 5
rahul(eff)= 1
we have given
arun = bipasha + rahul
arun - bipasha = rahul
so. ". ". = 1
there difference is 1
so arun has eff (3) and bipasha has (2)

Arun can do a certain work in the same time in which Bipasha and Rahul...
Given:

Arun can do a work in the same time in which Bipasha and Rahul together can do it.

Arun and Bipasha together can do the work in 10 days.

Rahul can do the work alone in 50 days.

To find:

Bipasha alone can do the work in how many days.

Solution:

Let the total work be 1 unit.

Let the number of days taken by Bipasha alone to complete the work be 'b' days.

Since Arun can do the work in the same time as Bipasha and Rahul together,

Arun's 1 day work + Bipasha's 1 day work = Rahul's 1 day work

(1/b) + (1/10) = (1/50)

Multiplying by 50b, we get

5b + 25 = b

4b = 25

b = 25/4 = 6.25

Therefore, Bipasha alone can do the work in 6.25 or approximately 6.25 days.

Hence, the correct option is (c) 25 days.
