    Answer:

    A can fill the empty tank alone in ( 12/1 × 1 ) = 12 hours.

    Step-by-step explanation:

    let, ( A + B ) means a and B work together.

    ( A + b ) can fill an empty tank in 8 hours and after 2 hours B was stopped. That means first 2 hours A and B worked together.

    ( A + b ) can fill a 2/8 = 1/4 part in 2 hours.

    after 2 two hours, A fill the remaining part of tank which is ( 1 – 1/4 ) = 3/4 in ( 11- 2) = 9 hours

    It means A can fill ( 3/4 × 1/9 ) = 1/12 part in 1 hour.

    Therefore, A can fill the empty tank alone in ( 12/1 × 1 ) = 12 hours.
