তিনটি ক্রমিক বিজোড় সংখ্যার প্রথমটির 1/3 অংশ যদি তৃতীয় সংখ্যার 1/5 অংশের চেয়ে 2 বেশি।
Calculation:
ধরি, তিনটি ক্রমিক বিজোড় সংখ্যা যথাক্রমে x, x + 2 এবং x + 4, অতএব
প্রশ্ন অনুযায়ী
x × (1/3) = (x + 4) × (1/5) + 2
⇒ x/3 = (x + 4 + 10)/5
⇒ 5x = 3x + 42
⇒ 5x – 3x = 42
⇒ 2x = 42
⇒ x = 21
∴ দ্বিতীয় বিজোড় সংখ্যা= x + 2 = 21 + 2 = 23
