Best answer

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 x X = Rs 600

x = Rs (60 x 100/25 ) = Rs 2400

Thus, she had Rs 2400 in the beginning.
