\(यदि (A={x:x\) is a letter in the word LEVEL}), तो (A) में कितने तत्व हैं?
\(If (A={x:x\) is a letter in the word LEVEL}), how many elements are in (A)?
Explanation opens after your attempt
C. (3)
Concept
The word (LEVEL) has letters (L,E,V,E,L).
Why this answer is correct
Repeated (L) and (E) are counted once each.
Exam Tip
The distinct elements are (L,E,V), so the number is (3). चरण 1: शब्द (LEVEL) में अक्षर (L,E,V,E,L) हैं। चरण 2: दोहराए गए (L) और (E) एक-एक बार गिने जाएँगे। चरण 3: अलग-अलग तत्व (L,E,V) हैं, इसलिए संख्या (3) है।
