দুটি সংখ্যার অনুপাত = 5 : 7
যখন প্রতিটিতে 6 যোগ করা হয়, তখন নতুন অনুপাত হয় = 3 : 4
গণনা:
ধরা যাক সংখ্যাদুটি হল 5x এবং 7x
প্রশ্ন অনুযায়ী,
⇒ \(\frac{5x+6}{7x+6}=\frac{3}{4}\)
⇒ 4(5x + 6) = 3(7x + 6)
⇒ 20x + 24 = 21x + 18
⇒ 21x – 20x = 24 – 18
⇒ x = 6
প্রথম সংখ্যা = 5x = 5 × 6 = 30
দ্বিতীয় সংখ্যা = 7x = 7 × 6 = 42
অতএব, সংখ্যা দুটি হল 30 এবং 42
