Raul is building a house
on day 1, he uses 3 bags of cement
on each of the following 3 days, he uses 3 times the number of bags used the previous day
how many bags of cement does he use in the last 3 days?

117 bags

Step-by-step explanation:

First day number of bags used by Raul=  3 bags

  We have to calculate the number of bags next three following days

On second day, number of bags used by Raul= 3×3=9

similarly, on third day number of bags used by Raul= 9×3=27

similarly, on fourth day number of bags used by Raul= 27×3=81

 Hence, the total number of bags used by Raul= 9+27+81=117

Hence, the correct answer is 117
