Answer :
Certainly! Let's go through the problem step by step.
1) Write a mathematical expression:
First, we need to identify all the given values:
- Weekly earning: Rs. 6000
- Food expense: Rs. 250
- Transportation expense: Rs. 75
Next, we calculate the total weekly expenses by adding the expenses for food and transportation.
```math
\text{Total expense} = \text{Food expense} + \text{Transportation expense}
```
Plugging in the given values:
```math
\text{Total expense} = 250 + 75
```
2) How much money does he save in a week?
First, we solve the total expenses calculated above:
```math
\text{Total expense} = 250 + 75 = 325
```
Next, we determine the amount of money Mr. KSIST saves each week by subtracting the total expenses from his weekly earning.
```math
\text{Money saved} = \text{Weekly earning} - \text{Total expense}
```
Plugging in the values:
```math
\text{Money saved} = 6000 - 325
```
Solving for the money saved:
```math
\text{Money saved} = 6000 - 325 = 5675
```
So, the results are:
1. The mathematical expression for total expense is:
```math
\text{Total expense} = 250 + 75
```
2. The amount of money Mr. KSIST saves in a week is:
```math
Rs. 5675
```
