Calculate Mathematics Marks
The problem asks us to find the marks scored in Mathematics, given that it was 20% more than the marks scored in Physics. The Physics score is provided as 72.
Step-by-Step Solution
- Identify the known values:
- Physics Marks = 72
- Mathematics Marks are 20% more than Physics Marks.
- Calculate Mathematics Marks:
To find the Mathematics marks, we need to calculate 120% of the Physics marks, because it's 20% *more* than the Physics score.
Mathematics Marks = Physics Marks $\times$ (100% + 20%)
Mathematics Marks = $72 \times (1 + 0.20)$
Mathematics Marks = $72 \times 1.20$
- Perform the calculation:
Mathematics Marks = $86.4$
Therefore, the student scored 86.4 marks in Mathematics.
