Hints: এখানে প্রতিক্ষেত্র টোটাল যে টাকা টি সবার মাঝে ভাগ করা হয়েছে তা একই। ধরি, মানুষের অর্জিনাল সংখ্যা x এবং amount if money y তাহলে, xy = (x + 4) (y - 16) = (x - 4) ( y + 24) xy = xy + 4y - 16x - 64 = xy - 4y + 24x - 96 0 = 4y - 16x - 64 = - 4y + 24 x - 96 এখন, 0 = y - 4x - 16 y = 4x + 16 আবার , 0 = - y + 6x - 24 y = 6x - 24 অর্থাৎ, 4x + 16 = 6x - 24 2x = 40 x = 20
