यदि (a=73) और (r=3), (q=7), तो (b) का मान क्या होगा?
If (a=73), (r=3), and (q=7), what is the value of (b)?
Explanation opens after your attempt
C. (10)
Concept
Substitute in (a=bq+r): (73=7b+3).
Why this answer is correct
(70=7b), so (b=10).
Exam Tip
To find an unknown divisor, subtract the remainder first. चरण 1: (a=bq+r) में मान रखें: (73=7b+3)। चरण 2: (70=7b), इसलिए (b=10)। चरण 3: अज्ञात भाजक निकालते समय पहले शेषफल घटाएं।
