Q 1) Howmany students have scored lowest in more than one subject ?
solution : In HINDI - vimal , ENG - Deepak , MATH -bhaskar , s.st - charu ,SCIEN - vimal , SANS -charu , PHY - vimal are scored lowest . finally vimal - 4 subjects ,Deepak -1 subject, Bhaskar - 1 subject , charu - 2 subjects scored lowest Ans = 2
Q 2) Who has scored higest marks in all subjects together ?
solution : Here we need not to calculate the total marks of individual students .we just do it by finding highest scorer in each subject. In HINDI - Goutham , ENG - Bhaskar , MATH -Anupama , s.st - Anupama ,SCIEN - deepak , SANS -bhaskar , PHY - anupama are scored Highest . finally Goutham - 1 subject ,anupama - 3 subjects, Bhaskar - 2 subjects , deepak - subjects scored highest. Ans = anupama
Q 3)What are the percentage of marks goutham marks in all subjects together ?
solution : Sum of marks obatained / total marks92+82+81+79+49+38+61 / 600 = 482/600 (10 % 600 =60 ;1 % 600= 6 ) 80% =480 remaining = 2 (6/3=1/3%) finally Ans = 80.33 %
Q 4) Marks obtained by charu in hindi what percentage of marks marks obtained by anupama in same subject ?
solution : ( 64 / 85 ) * 100 = (1 % 85 = 0.85 ; 50 % 85 = 42.5 ; 25 % 85 = 21.25 ) 75 % 85 = 42.5 + 21.25 = 63.75 remaining =0.25 (0.85 / 3 = 0..33 % ) finally Ans = 75.33 %
Q 5) what are the average marks obtained by all students together in science ?
solution : sum of marks / number of subjects = 65+62+55+70+49+44/ 6 = 345 / 6 Ans = 57.5
