Solution: প্রশ্নে বলা হচ্ছে যে, আরিফের বর্তমান বয়স বাবুর বয়সের 5 গুণ । কিন্তু 7 বছর পর তার বয়স বাবুর বয়সের 3 গুণ হবে । আরিফের বর্তমান বয়স কত ? মনে করি, বাবুর বর্তমান বয়স x বছর আরিফের বর্তমান বয়স = 5x বছর প্রশ্নমতে, (5x + 7) = 3(x + 7) => 5x + 7 = 3x + 21 => 5x - 3x = 21 - 7 => 2x = 14 x = 14/2 = 7 আরিফের বর্তমান বয়স = 5x = 5 7 = 35 বছরRelated questions
