Answer 1

Answer:

Please mark this answer as the brainliest answer

$A's \: \: one \: days \: work = \frac{1}{60}$

$A + B 's \: one \: days \: work = \frac{1}{35}$

$B's \: one \: day's \: work = \frac{1}{35} - \frac{1}{60}$

$= \frac{12}{420} - \frac{7}{420}$

$= \frac{5}{420}$

$B \: \: can \: \: do \: \: the \: work \: in = \frac{420}{5} = 84$

B can do the work in 84 days .
