Directions (next five questions): These questions consits of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and choose the appropriate option.
(Applicable only to the following question)
In how many days can ‘B’ alone complete the work
I. A, B and C together can complete the work in 3 9/13 days
A and B together can complete the work in 4 4/5 days. B
And C together can complete it in 6 6/7 days
II. A, B and C together can compete the piece of work in
3 9/13 days. A and C together can complete the work in 5 1/3 days.
If the data in statement I alone are sufficient to answer the question while the data in statement II are not sufficient to answer the question. If the data in statement II alone are sufficient to answer the question while the data in statement I are not sufficient to answer the question. If the data either in statement I alone or statement II alone are sufficient to answer the question. If the data both statements I and II together are not sufficient to answer the question. If the data in both statement I and II are necessary to answer the question. Explanation: From statement I,
(A+B+C)'s 1 day's work =13/48
(A+2B+C)'s 1 day's work
=5/24+7/48= 10+7/48=17/48
ஃ B's 1 day's work= 17/48-13/48= 4/48=1/12
ஃ Required time = 12days
From statement II,
(A+B+C)'s day's work= 13/48
(A+C)'s 1day's work =3/16
ஃ B's 1day's work =13/48-3/16=13-9/48
=4/48=1/12
ஃ Required time = 12days
