প্রশ্নে বলা হচ্ছে, বর্তমানে জামালের বয়স আরিফের বয়সের দ্বিগুণ। ৩০ বছর পর সে আরিফের চেয়ে ১৮ বছরের বড় হবে । জামালের বর্তমান বয়স কত? ধরি, Arif-এর বর্তমান বয়স = x বছর, এবং Jamal- এর বর্তমান বয়স= 4x বছর প্রশ্নমতে, 4x + 30 = x + 30 + 18 ⇒ 3x = 18 ∴ x = 6 ∴ Jamal-এর বর্তমান বয়স = 4x = 4 × 6 = 24 বছর।Related questions
