Monthly average and a half-average month: A business has total annual sales of ₹132000. If June's sales were half of the monthly average, what were the sales in June?

Introduction / Context:Find monthly average from annual total, then take half for June.

Given Data / Assumptions:

• Annual sales = ₹132000
• Months = 12
• June = half of monthly average

Concept / Approach:Monthly average = total / 12. Half of that is the required June sales.

Step-by-Step Solution:Monthly average = 132000 / 12 = ₹11000June sales = 11000 / 2 = ₹5500

Verification / Alternative check:If one month is at half-average, another could be above average to keep the annual sum correct; the question asks only for June's value, which is ₹5500.

Why Other Options Are Wrong:₹7200, ₹6300, ₹5600, ₹8400 are not half of ₹11000.

Common Pitfalls:Dividing by 6 instead of 12; or halving the annual total directly by mistake.

Final Answer:₹ 5500
