Comments

It's always taken as the remaining amounts percentage unless specified.

Answer 2

Let me consider the initial amount to be 100 percent then
After the 40% expense it reduces to 60%
Then 60 - (60×25/100) = 45%
Then 45 - (45×15/100) = (153/4)%
Then (153/4) - (153/4×5/100) = 36.3375%

So 36.3375% of the initial amount is given to be = 130500/- ie.,
(36.3375/100)×(initial amount) = 130500
Therfore initial amount = 3,59,133.13/-
