Answer:
The number of each kind of apartment in the building is 130 Â .
Step-by-step explanation:
Given as :
The total number of floor in a building = 15
The number of apartment on each floor = 26
So, The total number of apartment = 26 × 15 = 390
The number of kinds of apartment in the building is 3 , Â i.e 1-bedroom , Â Â Â Â Â Â Â 2-bedroom , 3-bedroom
Let The number of each kind of apartment in building = x
So, According to question
The number of each kind of building = [tex]\dfrac{\textrm Total number of apartment }{number of kinds of apartment}[/tex]
or, x = [tex]\frac{390}{3}[/tex]
∴  x = 130
Hence The number of each kind of apartment in the building is 130 Â . Answer
