Answer :
Given:
The total number of blocks = 164
Number of blocks used for the main part of the house = 100
Number of blocks used for the roof of the house = 50
Number of blocks used for the chimney of the house = 14
Solution:
The number of blocks used for the new house is also 164
Let the number of blocks used for the main part of the new house be x, roof be y, chimney be z
Then
x+y+z =164
110 + 34+20 = 164
