a) 4​

Answer 1

Answer:

8 days

Step-by-step explanation:

days in which a job is done by one man and two women = 12

therefore,

job done by 1 man in 1 day = 1/12

job done by 1 woman in 1 day = 1/12 × 1/2

1/24

job done by 1 man and 1 woman in 1 day

= 1/12 + 1/24

= 3/24

= 1/8

hence,

1 man and 1 woman will do the job in 8 days.
