To calculate the number of marks needed to get a score of 50, given that you scored 23 out of 50 on an assignment worth 50 and the final exam is out of 77, you can follow these steps:
1. Calculate the percentage you scored on the assignment: `(23/50) * 100 = 46%`
2. Calculate the remaining percentage needed to reach a score of 50: `50% - 46% = 4%`
3. Convert the remaining percentage to a decimal: `4/100 = 0.04`
4. Calculate the equivalent marks needed to get the remaining percentage on the final exam: `0.04 * 77 = 3.08`
Therefore, you would need to score approximately 3.08 marks on the final exam to get a total score of 50.
