Quantitative Aptitude (SBI-CL) Time and work

A takes 20% more time than B and they both completes the work in $8\frac{2}{11}$ days. Find in how much time A can do the half of the work.

9 days

18days

12days

15days

21days

Let B takes X days to complete the
whole work alone
So, A takes 1.20X to complete the whole
work alone.
A.T.Q,

On solving this we get,
X = 15 days
So, A takes 1.20 × 15 = 18 days to
complete whole work alone
A completes half the work in 18÷2 = 9 days.
