Question

if it takes 60 minutes for 9 people to paint 5 walls thhen how many minutes does it take for 4 people to paint 6 walls

Answer 1

--  9 people paint 5 walls in 60 minutes

--  9 people paint (5 / 5) = 1 wall in (60 / 5) = 12 minutes

--  (9 / 9) = 1 person paints 1 wall in (9 x 12) = 108 minutes

-- 1 person paints (1 x 6) = 6 walls in (108 x 6) = 648 minutes

-- (1 x 4) = 4 people paint 6 walls in (648 / 4) = 162 minutes .
