(2) Mr. Ksist earns Rs. 6000 in a week. He spends Rs. 250 for food and Rs. 75 for transportation.

i) Write a mathematical expression to represent his weekly savings.
ii) How much money does he save in a week?



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
```
