Answer 1

180 people live in building , Block B has largest number  = 60 , 35 people live in Block D

Step-by-step explanation:

Circle has 360° Angle

Block B - 120°

Block C - 80°

Block D  - 70°

Block A  =  ?

A + B + C + D = 360°

=> A + 120 + 80 + 70 = 360°

=> A = 90°

People in Block A = (90 /360) * total people

=> 45 = (1/4) * total People

=> Total People = 180

Block B has largest number  = (120/360) * 180 = 60

People in Block D = (70/360) * 180 = 35
