Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi =
half of the fence
pragnesh and roghui = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
qazi and roghui =
quarter of the fence
time taken when they all work together
=
+
+ ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
= ![\frac{13}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B12%7D)
= ![\frac{12}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B13%7D)
= 0.9231 × 60(mins)
= 55.4 mins
