Solution

Let the money Gaurav inherited be equal to $X$

So, his hostel expenses equal $0.4X$

Expenses on books and stationery is $0.2X$

Remaining amount is $X - 0.4X - 0.2X = 0.4X$

Transport expenses is $50% of 0.4X = 0.2X$

Remaining amount is $0.4X - 0.2X = 0.2X$

He saves $50%$ of it, that is $0.1X$ and it equals $450$.

So, the value of $X$ is $450/0.1 = 4500$

$= 4500$
