Correct Answer

A. (A) को fix करके (B) की two possible circular positions देखेंFix (A) and check the two possible circular positions of (B)

Step 1

Concept

After removing circular rotation, positions with fixed distance are counted. In exams fix one object first for circular distance.

Step 2

Why this answer is correct

The correct answer is A. (A) को fix करके (B) की two possible circular positions देखें / Fix (A) and check the two possible circular positions of (B). After removing circular rotation, positions with fixed distance are counted. In exams fix one object first for circular distance.

Step 3

Exam Tip

Circular rotation हटाने के बाद fixed distance वाली positions गिनी जाती हैं। परीक्षा में circular distance में पहले one object fix करें।
