Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Simil
vlada-n [284]

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 = \frac{1}{2} half of the fence

pragnesh and roghui = \frac{1}{3}

qazi and roghui = \frac{1}{4} quarter of the fence

time taken when they all work together

= \frac{1}{2} + \frac{1}{3} + \frac{1}{4}

= \frac{13}{12}

= \frac{12}{13}

= 0.9231 × 60(mins)

= 55.4 mins
