প্রশ্নে বলা হচ্ছে, 'A' এর আয় 'B' এর চেয়ে 20% বেশি । 'B' এর আয় 'C' এর চেয়ে 25% কম । 'A' এর আয় 'C' এর আয় অপেক্ষা শতকরা কত কম ? ধরি, 'C' এর আয় 100 টাকা 'B' এর আয় = ( 100-25% of 100 ) টাকা = ( 100 - 25 ) টাকা = 75 টাকা 'A' এর আয় = ( 75+20% of 75 ) টাকা = ( 75 + 20×75/100 ) = ( 75 + 15 ) টাকা = 90 টাকা অতএব, 'C' হতে 'A' এর আয় কম = 100 - 90 = 10 টাকা শতকরা পরিমাণ = ( 10×100/100)% = 10%Related questions
