Bye bye till next time to face more Maths questions! ) Every subject has its own difficulties and I hope you know what the difficulties of Maths are like, and I hope you have learnt something new. I will appreciate all your corrections, suggestions and ratings. This was a nice question to end with, wasn't it? Maths is my favourite subject and if you have any trouble with the above questions, do not hesitate to ask me. Score in 9th subject = Total mark after 9 subjects - Total mark after 8 subjects Therefore, his total mark after 9 subjects was 441. Therefore, his total mark after 8 subjects was 432.Īverage = Sum of all values / Number of values His total mark after 8 subjects was:Īverage = sum of all values / number of values We know that the average is equal to the sum of all values divided by the number of values. So, Number of students who like only Maths = 10 - 7 = 3, and Number of students who like only English = 25 - 7 = 18. Similarly, the number of students who like only English is the number of students who like both subtracted from the number of students who like English. It's apparent that the number of students who like only Maths is the number of students who like both English and Maths subtracted from the number of students who like Maths.
Total Number of Children = Number of children who like Maths + Number of Children who like English - Number of children who like both subjects + Number of children who like neither or x = Number of children who like only Maths + Number of children who like only English + Number of children who like both subjects + Number of children who like neither subject We know that 7 like both subjects and 17 like neither, but we do not know how many like ONLY Maths and how many like ONLY English.
