Difficulty: Easy
Correct Answer: ₹ 72000
Explanation:
Introduction / Context:
We convert annual income to monthly, apply a fixed spending percentage per month, and then scale to 8 months. This is a direct proportional calculation without compounding.
Given Data / Assumptions:
Concept / Approach:
Compute monthly spend first (a constant 25% each month), then multiply by 8. No seasonal or variable spending is implied, so linear scaling is valid.
Step-by-Step Solution:
Verification / Alternative check:
Direct fraction method: 8 months is 8/12 of the year; annual spend at 25% = 0.25 * 432,000 = 108,000; 8/12 of 108,000 = 72,000. Same result.
Why Other Options Are Wrong:
Common Pitfalls:
Mistaking ₹4.32 lakh for ₹432,00 (missing a zero) or applying 25% to the annual total and then mishandling the 8/12 factor.
