Correct Answer

A. 0

Step 1

Concept

Write the number as (7q+6).

Step 2

Why this answer is correct

Adding 1 gives (7q+7=7(q+1)), so the remainder is 0.

Step 3

Exam Tip

If the remainder is one less than the divisor and 1 is added, divisibility becomes exact. चरण 1: संख्या को (7q+6) लिखें। चरण 2: 1 जोड़ने पर (7q+7=7(q+1)), इसलिए शेषफल 0 होगा। चरण 3: शेषफल भाजक से 1 कम हो और 1 जोड़ा जाए, तो संख्या पूर्णतः विभाजित हो जाती है।
