Question

Sarah spends Rs 4000 from her salary. If this is 80% of her salary. What is her salary? How much did she save?

(pls answer)​

Answer 1

Given :-

Spending of sara= 4000

Percentage of spent money = 80%

To Find

We have to find the salary and the saving of sarah

Solution :-

Let the salary Sarah be x

Now 80% of her salary = 4000

$:\implies\sf\ x\times 80\%= 4000\\ \\ \\ :\implies\sf\ \ x\times \dfrac{80}{100}= 4000\\ \\ \\ :\implies\sf\ 80x= 4000\times 100\\ \\ \\:\implies\sf\ x= \dfrac{\cancel{4000}\times 100}{\cancel{80}}\\ \\ \\:\implies\sf\ x= 50\times 100\\ \\ \\ \underline{\boxed{\sf\ x= 5000}}$

$\underline{\therefore\sf Salary \ of\ Sarah= 5000Rs}$

Saving = Salary - Spending

Saving = 5000-4000

→ 1000

$\underline{\dag\it\ Saving \ of\ Sarah= 1000Rs}$

Answer 2

Answer:

★ Given

• ⇒ Spending money by Sara = ₹4000
• ⇒ Percent of spent Money = 80%

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ To Find

• ⇒ Salary of Sarah
• ⇒ Saving money from his salary

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ Solution

⇒ Suppose his salary is ₹ "x"

⇒ And she spends 80% of the salary.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

So,

Firstly we Find the Salary

$\red\implies \sf \pink{x × 80 \%} = \purple {4000}$

$\red\implies \sf\pink{x × \dfrac{80}{100}} = \purple{4000}$

$\red \implies \sf \pink{\dfrac{80x}{100}} = \purple{4000}$

$\red\implies \sf \pink{80x} = \purple {4000 \times 100}$

$\red \implies \sf \pink{80x} = \purple {400000}$

$\red\implies \sf\cancel \dfrac \pink{400000} \pink{80}$

$\red \implies \sf \pink{₹ \: 5000}$

$\large\boxed{ \frak \purple{Salary} = \pink{₹ 5000}}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Now we Find the saving money of sarah

Saving = Salary - Spent Money

So,

$\red \implies \sf \purple{Saving} = \pink{5000 - 4000}$

$\red \implies \sf \purple{Saving} = \pink {₹ \: 1000}$

$\Large\boxed {\frak \pink{Saving} = \purple {₹ \: 1000}}$

★ Therefore

⇒ The Salary of Sarah is 5000 rupees.

⇒ And his saving is 1000 rupees.
