মোট বিক্রিত টিকিটের সংখ্যা 30000 টি 30 টাকা দরে টিকিট বিক্রি হয়েছে (30000 এর 1/4 অংশ) = 7500 টি 25 টাকা দরে টিকিট বিক্রি হয়েছে (30000 এর 1/3 অংশ) = 10000 টি অতএব 30 টাকা ও 25 টাকা দরে মোট বিক্রিত টিকিটের সংখ্যা = (7500 + 10000) টি = 17500 টি অতএব বাকি টিকিটগুলো অর্থাৎ 20 টাকা দরে বিক্রিত টিকিটের সংখ্যা = (30000 - 17500)টি = 12500 টি

Facts: Janet, a housewife standing at her balcony, was struck on the head by a ball that flew out of a cricket field across her home. Janet sues the District Cricket Association (DCA), the owner of the cricket field for public nuisance and negligence on the ground that the field did not have a fence high enough to prevent such occurrence. District Cricket Association (DCA) claims that only about 10 balls had escaped the field in the previous 10 years and it was therefore an unforeseeable risk. Is there a duty on the part of the District Cricket Association (DCA) to prevent the risk? Is the District Cricket Association (DCA) liable to compensate Janet?
