16 questions, answered with the actual numbers

Each page answers one question in its first sentence, then shows the working, a full table of variants, and the formula behind it. Nothing is rounded to a marketing figure and nothing is left as “it depends”.

These pages exist because most search results answer a numeric question with a paragraph of caveats and a lead form. Here the number comes first — Rs 26,035 a month for a Rs 30 lakh, 20-year home loan at 8.5%; Rs 12,75,000 of tax-free salary under the new regime; 23, not 25, as the Indian BMI overweight cut-off — and the reasoning comes after it.
