A person's income increases by 20%. His expenditure increases by 15% and his savings increase by 35%. What percentage of his original income did he save?
Correct Answerसही उत्तर
B. 25% / 25%
Explanationव्याख्या
Let original income = 100 and savings = x.
Then expenditure = 100 − x.
New income = 120, new savings = 1.35x and new expenditure = 1.15(100 − x).
So 1.35x + 1.15(100 − x) = 120.
Solving gives x = 25.
Hence original savings were 25% of income.
मूल आय 100 और बचत x मानें।
व्यय = 100 − x।
नई आय 120, नई बचत 1.35x और नया व्यय 1.15(100 − x) होगा।
समीकरण हल करने पर x = 25 मिलता है।
अतः मूल बचत आय का 25% थी।
