If (a=3!) and (b=2!), what is the value of (a+b)?यदि (a=3!) और (b=2!), तो (a+b) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 88
Here, a=3!=3×2×1=6 and b=2!=2×1=2. Therefore, a+b=6+2=8, so option C is correct. The value 6 is only the value of a, not their sum. Exam tip: Evaluate each factorial separately before performing the required operation.यहाँ a=3!=3×2×1=6 तथा b=2!=2×1=2 है। अतः a+b=6+2=8, इसलिए सही विकल्प C है। 6 केवल a का मान है, योग का नहीं। परीक्षा टिप: पहले प्रत्येक फैक्टोरियल का मान अलग-अलग निकालें, फिर दी गई संक्रिया करें।
