यदि (a=64), (b=7), तो (a=bq+r) में सही (q) कौन-सा है?
If (a=64) and (b=7), which is the correct (q) in (a=bq+r)?
Explanation opens after your attempt
B. (9)
Concept
Check multiples of (7).
Why this answer is correct
\(7 \times 9=63\) and \(7 \times 10=70\), which is greater than (64). So (q=9).
Exam Tip
Take the quotient for which the product does not exceed the number. चरण 1: (7) के गुणज देखें। चरण 2: \(7 \times 9=63\) और \(7 \times 10=70\), जो (64) से बड़ा है। इसलिए (q=9)। चरण 3: भागफल वही लें जिससे गुणनफल संख्या से अधिक न हो।
