Solution

The correct option is D
21.57%
Total readership of ABC =x+3+1.2+0.8=9.7 lakh=>x=4.7 lakh
Total readership of DEF =y+3+1.2+2.3=9.1 lakh=>y=2.6 lakh
Total readership of GHI =z+1.2+2.3+0.8=8.9 lakh=>z=4.6 lakh
Therefore, number of people reading at least 1=4.7+2.6+4.6+3+1.2+0.8+2.3=19.2lakhAs a % of total population=19.289×100=21.57%

ABC की कुल पाठक संख्या =x+3+1.2+0.8=9.7 लाख
=>x=4.7 लाख
DEF की कुल पाठक संख्या=y+3+1.2+2.3=9.1 लाख
=>y=2.6 लाख
GHI की कुल पाठक संख्या=z+1.2+2.3+0.8=8.9 लाख
=>z=4.6 लाख
इसलिए, पढ़ने वालों की संख्या कम से कम 1=4.7+2.6+4.6+3+1.2+0.8+2.3=19.2 लाख
कुल जनसंख्या के% के रूप में=19.289×100=21.57%
