Answer 1

The number of each kind of apartment in the building is 130 .

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 , i.e 1-bedroom , 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 =
`(\textrm Total number of apartment )/(number of kinds of apartment)`

or, x =
`(390)/(3)`

∴ x = 130

Hence The number of each kind of apartment in the building is 130 . Answer
