Consider the following for the next three (03) items that follow: Study the following Pie charts: Chart-I (Number of houses: 1,20,000): Pucca 110°, Semi-pucca 210°, Kutcha 40°. Chart-II (Population: 21,00,000): Living in kutcha houses 20°, Houseless 70°, Living in pucca houses 60°, Living in semi-pucca houses 210°. Chart-III (Number of families: 3,60,000): Living in pucca houses 70°, Living in kutcha houses 185°, Living in semi-pucca houses 85°, Houseless 20°. If 5000 more Kutcha houses are built, then what will be approximate change in angle for Kutcha houses in Pie Chart-I?
- A11°
- B13°
- C15°
- D23°
Explanation
Kutcha houses now: (40/360)×120000 = 13333; with 5000 more, 18333 out of 125000 houses gives angle (18333/125000)×360 ≈ 52.8° ≈ 53°. Change ≈ 53 − 40 = 13°, option (b).
