Ramy and Adel took an exam. Ramy got 10 percent of the questions correct and Adel scored 79 out of 100. Who got the higher mark and how many more marks did they receive?

So we’re told about the performance of two students in an exam. For Ramy, we’re told this as a percentage, whereas for Adel, we’re told how many marks were scored out of the total. In order to work out who got the higher mark and also how many more marks they received, we need to know what score Ramy got out of the total. We need to convert Ramy’s percentage to an actual score out of 100.

So Ramy got 10 percent of 100 questions correct. In order to find 10 percent of a number, we need to divide it by 10. 100 divided by 10 is 10. Therefore, Ramy scored 10 out of 100. Remember, Adel scored 79 out of 100. So we can see straight away that Adel was the higher scorer.

To find how many more marks Adel received, we need to subtract Ramy’s score from Adel’s. 79 minus 10 is equal to 69. The higher scorer was Adel by 69 marks.
