Answer 2

meeta, Veena & Kamlesh can sweep a playground in 4, 6, 8 hours respectively

• Work done by Meeta in 1 hours = $\frac{1}{4}$
• Work done by Veena in 1 hours = $\frac{1}{6}$
• Work done by Kamlesh in 1 hours = $\frac{1}{8}$

Work done be all of them working together for 1 hours =

$\frac{1}{4} + \frac{1}{6} + \frac{1}{8}$

$= \frac{6 + 4 + 3}{24} </p><h3> \\= \frac{13}{24}$

Thus, $= \frac{13}{24}$portion of the ground can sweep in 1 hour working together
