It takes 33 days for 6 women or 17 men to paint a wall.
The work rate of 12 women and 32 men can be calculated by converting the work rate of 6 women to men,
which is 17/6 men/woman.
The total work rate of the group of 12 women and 32 men is then 34 men.
Therefore, it would take (17*33)/34 = 25.5 days for 12 women and 32 men to paint three walls at the same rate
