Answer 1

let the ravanas salary= x
x-(3/10x+3/10x+24/100x)=2500
x-(84x/100)=2500
16x/100=2500
x=2500*100/16
x=625*25
x=15625

ravamas salary=Rs.15625

Answer 2

Given :

Ravana spends 30% of his salary on house rent, 30% of the rest he spends on his children's education and 24% of the total salary he spends on clothes.

To Find:

After his expenditure, he is left with rs. 2500. What is ravana's salary?

Solution:

Let Ravana's Salary be x

Ravana spends 30% of his salary on house rent

So, House rent = 0.3x

Remaining salary = x-0.3x=0.7x

He spends 30% of the rest he spends on his children's education

He spend on Children's education = 0.3(0.7)x=0.21x

He spends 24% of the total salary on clothes.

he spends on clothes = 0.24x

Total expenditure = 0.3x+0.21x+0.24x=0.75x

He left with amount = x-0.75x=0.25x

We are given that he is left with rs. 2500.

So, 0.25x=2500

$x=\frac{2500}{0.25}$

x=10000

Hence Ravana's salary is Rs.10000
