जर 1156 = 34 तर 2916 = ?

The correct answer is Option A (54).

Key Points:
• This is a mathematical analogy question based on finding square roots.
• Understanding the given relation:
• The problem states: 1156 = 34.
• Mathematically, 34 × 34 = 1156. This means 34 is the square root of 1156 (√1156 = 34).
• Solving for 2916:
• We need to find the square root of 2916 (i.e., a number which when multiplied by itself gives 2916).
• Let's use the unit digit trick: The number 2916 ends in 6. So its square root must end in either 4 or 6 (since 4²=16 and 6²=36). This keeps options 54, 44, 64, and 36 in play.
• Let's approximate:
• 50 × 50 = 2500 (2916 is a bit larger than 2500).
• 60 × 60 = 3600 (2916 is much smaller than 3600).
• Therefore, the answer must be in the early 50s. The only option ending in 4 or 6 in this range is 54.
• Verification: 54 × 54 = 2916.
• Option 1 is correct.
• Key Takeaway: Identify the mathematical relationship: 34 is the square root of 1156. By estimating (50² = 2500), 54 is the square root of 2916.
