Answer» Answer :- Sushma had RS 2400 in the beginning. To find :- The amount of money she had in the beginning. Step-by-step explanation :- Here, we have to find the amount of money Sushma had before spending 75% on her salary. It has been given that :- Sushma spent 75% of her salary. Hence, The percentage of money left with her = 100% - 75% = 25% Now, it has been given that :- After spending 75% of her salary, Sushma is left with Rs 600. It means, that 25% of Sushma's salary is Rs 600. Let the amount of money Sushma had in the beginning be "x". ------------------------------------ $\longmapsto\sf25\% \: of \: x = 600$ Converting 25% into fraction, $\longmapsto\sf \dfrac{25}{100} \times x = 600$ MULTIPLYING 25/100 with x, $\longmapsto\sf \dfrac{25x}{100} = 600$ Transposing 100 from LHS to RHS, changing it's sign, $\longmapsto\sf25x = 600 \times 100$ Multiplying 600 with 100, $\longmapsto\sf25x = 60000$ Transposing 25 from LHS to RHS, changing it's sign, $\longmapsto\sf x = \dfrac{60000}{25}$ Dividing 60000 by 25, $\longmapsto \underline{ \boxed{\sf x = 2400}}$ $\\$ The VALUE of x is 2400. Hence, Sushma had Rs 2400 in the beginning. ________________________________

Answer :-

To find :-

Step-by-step explanation :-

Here, we have to find the amount of money Sushma had before spending 75% on her salary.

It has been given that :-

Hence,

Now, it has been given that :-

------------------------------------

$\longmapsto\sf25\% \: of \: x = 600$

Converting 25% into fraction,

$\longmapsto\sf \dfrac{25}{100} \times x = 600$

MULTIPLYING 25/100 with x,

$\longmapsto\sf \dfrac{25x}{100} = 600$

Transposing 100 from LHS to RHS, changing it's sign,

$\longmapsto\sf25x = 600 \times 100$

Multiplying 600 with 100,

$\longmapsto\sf25x = 60000$

Transposing 25 from LHS to RHS, changing it's sign,

$\longmapsto\sf x = \dfrac{60000}{25}$

Dividing 60000 by 25,

$\longmapsto \underline{ \boxed{\sf x = 2400}}$

$\\$
