Answer:Let,

A work alone in one day = 1/A= 1/20

A & B together work and complete the work in 12 days

so, 1/A + 1/B = 1/12

1/20 + 1/B = 1/12

1/B = 1/12 – 1/20

1/B = (20-12)/240

1/B = 8/240

1/B = 1/30

B = 30

So, that

B will work alone then, complete the work in 30daysIhopethatitwillhelpyouthanx
