This question is based on the Least Common Multiple (LCM) method. We will find the LCM of the numbers 4, 6 and 8.
4 = 2 x 2 =
6 = 2 x 3 = 2 x 3
8 = 2 x 2 x 2 =
So, LCM is =
Therefore, at every 24th houses, we will find all three trolls colors.
And 24 is the number of houses we will find all color trolls. Then in a group of 75 houses, it will occur thrice and at every 24th place. Means. 3 houses will have all color trolls.
The following lab team that has an unresolved problem on their hands is team 2 in which they calculated 0.395 J/gºC since they have higher percent error compared to the other team which only has 0.390 J/gºC. So the answer would be letter B - <span>team 2: calculates 0.395 J/gºC.</span>
