Answer 1

Let the amount of money which Chameli had in the beginning be x.

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 xx x = Rs 600`

`x = Rs(600 xx 100/25)` = Rs  2400

Thus, she had Rs 2400 in the beginning.
