Out of the three semester examinations, each with a total of 500 marks, a student secured average marks of 45% and 55% in the first and second semester examinations. To have an overall average of 60%, how many marks does the student need to secure in the third semester examination?
Correct
Answer : 2. 400
Explanation :
Total marks for three semester examinations = 3x 500 = 1500
Total required marks in three semester examinations = 60% of 1500
=( 3 x 500 x 60 ) / 100 = 900
Marks secured in first semester examination = 45 % of 500
=( 500 x 45 ) / 100 =225
Marks secured in third semester examination = 55 % of 500
=( 500 x 55 ) / 100 =275
Thus, the required marks in third semester examination
=900 – ( 225 + 275 ) =900 – 500 = 400
Incorrect
Answer : 2. 400
Explanation :
Total marks for three semester examinations = 3x 500 = 1500
Total required marks in three semester examinations = 60% of 1500
=( 3 x 500 x 60 ) / 100 = 900
Marks secured in first semester examination = 45 % of 500
=( 500 x 45 ) / 100 =225
Marks secured in third semester examination = 55 % of 500
=( 500 x 55 ) / 100 =275
Thus, the required marks in third semester examination
=900 – ( 225 + 275 ) =900 – 500 = 400
