Correct Answerसही उत्तर
C. ₹2,400 / ₹2,400
Explanationव्याख्या
Expenditure factor = 1.20 × 0.90 = 1.08.
Hence expenditure increases by 8%.
If 8% = ₹192, original expenditure = 192 × 100
8 = ₹2,400.
खर्च का गुणक = 1.20 × 0.90 = 1.08।
अतः खर्च में 8% वृद्धि होती है।
8% = ₹192, इसलिए मूल खर्च = ₹2,400।
