Mark and clean his father's office in 30 minutes his younger sister Lynn can clean the office in 40 minutes how long will it tak

egoroff_w [7]

we are given

Mark clean his father's office in 30 minutes

so, the amount of work done by Mark in 1 minute is $\frac{1}{30}$

younger sister Lynn can clean the office in 40 minutes

so, the amount of work done by younger sister Lynn in 1 minute is $\frac{1}{40}$

total work done by them in 1 minute is $\frac{1}{30}+\frac{1}{40}$

now, we can simplify it

$=\frac{4*1}{4*30}+\frac{3*1}{3*40}$

$=\frac{4+3}{120}$

$=\frac{7}{120}$

total time taken to complete same work is $\frac{120}{7} min$ ........Answer
