उत्तर
Let total money initially = x
Percentage of money spent by Chameli = 75%
It is given that after spending 75% of Rs x, she was left with Rs 600.
Therefore,
(100 − 75)% of x = Rs 600
Or, 25 % of x = Rs 600
`25/100` × x = Rs 600
x = Rs`(600 xx 100/25)`
x = Rs 2400
Thus, she had Rs 2400 in the beginning.
