Correct Answerसही उत्तर
C. ₹40,000 / ₹40,000
Explanationव्याख्या
Let income = 100%.
After spending 30% on food, 70% remains.
Rent = 20% of 70% = 14%, so 56% remains.
Education = 25% of 56% = 14%, leaving 42% as savings.
If 42% = ₹16,800, total income = 16,800 × 100
42 = ₹40,000.
आय 100% मानें।
भोजन के बाद 70% बचता है।
किराया = 70% का 20% = 14%, इसलिए 56% बचता है।
शिक्षा = 56% का 25% = 14%, अतः अंतिम बचत = 42%।
42% = ₹16,800, इसलिए कुल आय = ₹40,000।
