প্রশ্নে বলা হচ্ছে যদি 7, 13, p এবং g এর গড় 17 হয় তবে (p + 11) এবং (g - 9) এর Average কত হবে? প্রশ্নমতে, (7 + 13 + p + q)/4 = 17 ⇒ 20 + p + q = 68 [গড় = সংখ্যাগুলোর যোগফল/মোট সংখ্যা] ∴ p + q = 48 ∴ (p + 11 ) (q - 9) এর Average = {(p + 11 ) + (q - 9)}/2 = (p + 11 + q - 9)/2 = (p + q + 2)/2 = (48 + 2)/2 = 25Related questions
