Correct Answerसही उत्तर
C. 45% / 45%
Explanationव्याख्या
Let original income = 100.
Savings = 20 and expenditure = 80.
New income = 125 and new expenditure = 80 × 120
100 = 96.
New savings = 125 − 96 = 29.
Increase in savings = 29 − 20 = 9.
Percentage increase = 9
20 × 100 = 45%.
मूल आय 100 मानें।
बचत 20 और व्यय 80 होगा।
नई आय 125 और नया व्यय 96 होगा।
नई बचत = 29।
अतः बचत में वृद्धि = 9
20 × 100 = 45%।
