## she spent (1/4) + (1/3 * 3/4) + (2/5 * 1/2) = 19/30

so, 11/30 x = 5000

## Let her salary be x

Then 1/4 of x is salary i.e 1/4x
Then 1/3 of the remainder on food i.e 1/3× (1-1/4) on food =1/3×3/4=1/4
Then the rest is i.e 1-1/4-1/4 or 3/4-1/4=1/2
Then now amount on transport is 2/5×1/2=1/5
If she has 5000 left i.e 1-1/4-1/4-1/5=6/30 i.e 3/10
Then now we can say 3/10x=5000
Cross mulitiplying we get
X= 5000×10÷3
X=16666.67 naira
Thanks

## Well, it's a good thing she still has some money left! Let's do some calculations to find out her monthly salary.

If she spent 1/4 of her salary on rent, that means she has 3/4 left.

Then, if she spent 1/3 of the remaining money on food, she has 2/3 of the 3/4 left.

After that, if she spent 2/5 of the remaining money on transport, she has 3/5 of the 2/3 of the 3/4 left.

Now, we know that she has 5000 naira left. So we can set up the equation:

3/5 * 2/3 * 3/4 * salary = 5000

If you solve that equation, she must be earning 7500 naira as her monthly salary. That's a good amount of money, but I hope she remembers to save some for clown insurance!

## To find the woman's monthly salary, we will work backwards step by step.

Let's assume her monthly salary is "x" naira.

1. She spent 1/4 of her salary on rent:
Rent = 1/4 * x

2. The remaining salary after paying the rent:
Remaining Salary = x - Rent
= x - (1/4 * x)
= x - x/4
= 3x/4

3. She spent 1/3 of the remaining salary on food:
Food = 1/3 * Remaining Salary
= 1/3 * (3x/4)
= x/4

4. The remaining salary after spending on rent and food:
Remaining Salary = Remaining Salary - Food
= (3x/4) - (x/4)
= 2x/4
= x/2

5. She spent 2/5 of the rest on transport:
Transport = 2/5 * Remaining Salary
= 2/5 * (x/2)
= x/5

6. The remaining salary after spending on rent, food, and transport:
Remaining Salary = Remaining Salary - Transport
= (x/2) - (x/5)
= (5x/10) - (2x/10)
= 3x/10

Given that she has 5000 naira left, we can set up an equation based on the remaining salary:

Remaining Salary = 5000

3x/10 = 5000

To solve for x, we can multiply both sides of the equation by 10/3:

x = 5000 * 10/3

x = 16666.67 naira

Therefore, her monthly salary is approximately 16666.67 naira.
