Raza scored `30` marks in Maths, `x` marks in Science and `y` marks in English. What is his total score in these three subjects ?

Options

A. `30+x+y`
B. `30+x-y`
C. `x+y-30`
D. `30+30x+30y`

Answer

To find Raza's total score in the three subjects (Maths, Science, and English), we can follow these steps:

### Step 1: Identify the scores in each subject
- Raza scored 30 marks in Maths.
- He scored `x` marks in Science.
- He scored `y` marks in English.

### Step 2: Write the expression for total score
To find the total score, we need to add the marks from all three subjects together. The expression for the total score can be written as:
\[ \text{Total Score} = \text{Marks in Maths} + \text{Marks in Science} + \text{Marks in English} \]

### Step 3: Substitute the known values into the expression
Now, we substitute the known values into the expression:
\[ \text{Total Score} = 30 + x + y \]

### Step 4: Finalize the total score expression
Thus, the total score Raza achieved in Maths, Science, and English is:
\[ \text{Total Score} = 30 + x + y \]

### Summary
Raza's total score in the three subjects is \( 30 + x + y \).
