यदि (p=19q+16), तो (6p-20) को 19 से भाग देने पर शेषफल क्या होगा?
If (p=19q+16), what is the remainder when (6p-20) is divided by 19?
Explanation opens after your attempt
A. 0
Concept
The remainder of (p) is 16.
Why this answer is correct
The remainder of (6p-20) comes from \(6\times16-20=76\).
Exam Tip
Since \(76=19\times4\), the final remainder is 0. चरण 1: (p) का शेषफल 16 है। चरण 2: (6p-20) का शेषफल \(6\times16-20=76\) से मिलेगा। चरण 3: \(76=19\times4\), इसलिए अंतिम शेषफल 0 है।
