From Chart-I: Number of houses = 1,20,000
Angle for Pucca houses = 110°
From Chart-II: Population = 21,00,000
Angle for population living in Pucca houses = 60°
Formula used:
Part of total = (Angle / 360) × Total Value
Average = Total Value / Number of units
Calculations:
Number of Pucca Houses = (110 / 360) × 1,20,000
⇒ Number of Pucca Houses = (11 / 36) × 1,20,000
⇒ Number of Pucca Houses = 11 × (120000 / 36)
⇒ Number of Pucca Houses = 110000 / 3
Population Living in Pucca Houses = (60 / 360) × 21,00,000
⇒ Population Living in Pucca Houses = (1 / 6) × 21,00,000
⇒ Population Living in Pucca Houses = 3,50,000
Average Persons per Pucca House = Population Living in Pucca Houses / Number of Pucca Houses
⇒ Average Persons per Pucca House = 350000 / (110000 / 3)
⇒ Average Persons per Pucca House = (350000 × 3) / 110000
⇒ Average Persons per Pucca House = (35 × 3) / 11
⇒ Average Persons per Pucca House = 105 / 11
⇒ Average Persons per Pucca House ≈ 9.5454...
∴ The correct answer is option 3.
