Solution: প্রশ্নে বলা হচ্ছে, Faruk বশিরের চেয়ে 16 বছরের ছোট । 4 বছর পর বশিরের বয়স Faruk এর বয়সের দ্বিগুণ হবে । এখন ফারুকের বয়স কত ? ধরি, বশিরের বয়স x বছর এবং ফারুকের বয়স (x - 16) বছর । 4 বছর পর বশিরের বয়স হবে (x + 4) বছর এবং 4 বছর পর ফারুকের বয়স হবে ( x - 16 + 4) = ( x - 12) বছর প্রশ্নমতে, x + 4 = 2(x - 12) => x + 4 = 2x - 24 => 4 + 24 = 2x - x x = 28 বর্তমানে ফারুকের বয়স = x - 16 = 28 - 16 = 12 বছর ।Related questions
