question_answer 5)

                If Chameli had Rs 600 left after spending 75% of her money, how much did she have in the beginning?

Answer:

                Percentage of money left = 100% ? 75% = 25% \[\therefore \] If Chameli had Rs 25 left, then the money she had in the beginning = 100 \[\therefore \] If Chameli had Rs 1 left, then the money she had in the beginning \[=\frac{100}{25}\]  \[\therefore \]                 If Chameli has Rs 600 left, then the money she had in the beginning \[=\frac{100}{25}\times 600=2400\] Hence, the money she had in the beginning was Rs 2400.
