Solution: অনুবাদঃ Mahalil এর পিতার বয়স তার বয়স অপেক্ষা 3 গুণ বেশি । 8 বছর পর Mahalil এর পিতার বয়স তার বয়সের গুণ হবে । আরো 8 বছর পর Mahalil এর পিতার বয়স Mahalil এর বয়সের কয়গুণ হবে ? মনে করি, Mahalil এর বয়স x বছর তার পিতার বয়স হবে 3x বছর 8 বছর পর Mahalil এর বয়সে হবে = (x + 8) বছর এবং 8 বছর পর Mahalil এর পিতার বয়স হবে = (3x + 8) বছর এখন প্রশ্নানুসারে, (3x + 8) = (x + 8) => (3x + 8) = 5/2 (x + 8) => 6x + 16 = 5x + 40 x = 24. তাহলে (8 + 8) = 16 বছর পর Mahalil এর বয়স হবে (24 + 16) = 40 বছর এবং 16 বছর পর তার পিতার বয়স হবে = (3 24 + 16) = (72 +16 ) = 88 বছর তাহলে 8 + 8 = 16 বছর পর পিতার বয়স Mahalil এর বয়সের 88/40 বা গুণ ।Related questions
