A' gave 25% of an amount to 'B'. From the money 'B' got, he spent 30% on a dinner. Out of the remaining amount, the respective ratio between the amount B kept as savings and the amount he spent on buying a book is 5 : 2. If B bought the book for Rs.460/, how much money did A have at the beginning?
Correct Answer: Description for Correct answer:
Suppose, A had the money at the beginning = Rs. X
The amount ofmoney B got=\( \large x \times\frac{25}{100} = \frac{x}{4}\)
Cost price of book = Rs.460/-
Saving = \( \large 460 \times\frac{5}{2} = Rs.1,150\)/-
According to question,
\( \large\frac{x}{4}\times\frac{70}{100}\)=(1150 + 460)
\( \large x = \frac{1610 \times400}{70} = Rs.9,200/- \)
