Mrs. Bfoundari donated [tex]\frac{1}{5}[/tex] part of her money to a charity. She gave [tex]\frac{3}{10}[/tex] part to her son and [tex]\frac{1}{4}[/tex] part to her daughter from the remaining amount of money. If she gave Rs 1,80,000 to the charity, how much money did she give to her son and daughter each?

Solution:



Answer :

To solve the problem, let's break it down step by step.

### Step 1: Determine the Total Amount of Mrs. Bfoundari's Money
Given that Mrs. Bfoundari donated [tex]\(\frac{1}{5}\)[/tex] of her money to charity and the donation amount is Rs. 180,000, we can find her total money by setting up an equation:

[tex]\[ \text{Donation to charity} = \frac{1}{5} \times \text{Total Money} \][/tex]

Given:
[tex]\[ \frac{1}{5} \times \text{Total Money} = 180,000 \][/tex]

To find the Total Money, solve for it by multiplying both sides of the equation by 5:

[tex]\[ \text{Total Money} = 180,000 \times 5 \][/tex]
[tex]\[ \text{Total Money} = 900,000 \][/tex]

So, Mrs. Bfoundari’s total money is Rs. 900,000.

### Step 2: Calculate the Amount Given to Her Son
Mrs. Bfoundari gave [tex]\(\frac{3}{10}\)[/tex] of her total money to her son. The amount given to her son can be calculated as:

[tex]\[ \text{Money Given to Son} = \frac{3}{10} \times \text{Total Money} \][/tex]
[tex]\[ \text{Money Given to Son} = \frac{3}{10} \times 900,000 \][/tex]
[tex]\[ \text{Money Given to Son} = 270,000 \][/tex]

So, she gave Rs. 270,000 to her son.

### Step 3: Calculate the Remaining Money After Charity and Son's Share
First, calculate the total fraction of the money given to charity and her son:

[tex]\[ \text{Fraction Given to Charity and Son} = \frac{1}{5} + \frac{3}{10} \][/tex]
Convert these fractions to a common denominator (10):

[tex]\[ \frac{1}{5} = \frac{2}{10} \][/tex]
[tex]\[ \frac{2}{10} + \frac{3}{10} = \frac{5}{10} = \frac{1}{2} \][/tex]

This means half of the total money has been given away to charity and her son. Therefore, the remaining amount is:

[tex]\[ \text{Remaining Money} = \text{Total Money} \times (1 - \frac{1}{2}) \][/tex]
[tex]\[ \text{Remaining Money} = 900,000 \times \frac{1}{2} \][/tex]
[tex]\[ \text{Remaining Money} = 450,000 \][/tex]

### Step 4: Calculate the Amount Given to Her Daughter
Mrs. Bfoundari gave [tex]\(\frac{1}{4}\)[/tex] of the remaining money to her daughter. The amount given to her daughter can be calculated as:

[tex]\[ \text{Money Given to Daughter} = \frac{1}{4} \times \text{Remaining Money} \][/tex]
[tex]\[ \text{Money Given to Daughter} = \frac{1}{4} \times 450,000 \][/tex]
[tex]\[ \text{Money Given to Daughter} = 112,500 \][/tex]

So, she gave Rs. 112,500 to her daughter.

### Summary
- Total Money: Rs. 900,000
- Money given to her son: Rs. 270,000
- Money given to her daughter: Rs. 112,500
