60.00 |
Question 1 Explanation:
Given marks are in percentages.
Average marks obtained by all students in chemistry=Total marks /Number of students
Total marks=130 × 0.5 + 0.6 × 130 + 0.6 × 130 + 0.75 × 130 + 0.8 × 130 + 0.75 × 130
=520
Average =520/6=86.66
Average marks obtained by all students in chemistry=Total marks /Number of students
Total marks=130 × 0.5 + 0.6 × 130 + 0.6 × 130 + 0.75 × 130 + 0.8 × 130 + 0.75 × 130
=520
Average =520/6=86.66
Question 2 |
In which subject the performance of the students is worst in terms of percentage of marks?
Chemistry | |
Physics | |
Biology | |
English |
Question 2 Explanation:
Chemistry = (130 × 0.5 + 0.6 × 130 + 0.6 × 130 + 0.75 × 130 + 0.8 × 130 + 0.75 × 130) / 780 = 520/780=66.66
Physics = (120 × 0.8 + 0.7 × 120 + 0.85 × 120 + 0.65 × 120 + 0.7 × 120 + 0.56 × 120) / 720 = 511.2/720 =71
Biology = (60+40+80+90+85+80) / 600 = 72.5
English = (70+80+60+90+50+40) / 600 = 65
English subject is worst in terms of percentage.
Physics = (120 × 0.8 + 0.7 × 120 + 0.85 × 120 + 0.65 × 120 + 0.7 × 120 + 0.56 × 120) / 720 = 511.2/720 =71
Biology = (60+40+80+90+85+80) / 600 = 72.5
English = (70+80+60+90+50+40) / 600 = 65
English subject is worst in terms of percentage.
Question 3 |
What is the overall percentage of marks obtained by Amar?
70% | |
72% | |
60% | |
58.33% |
Question 3 Explanation:
Overall percentage of marks obtained by Amar= (1x150 + 0.6x130 + 0.7x120 + 0.4x100 + 0.8 x 100) / (150 + 130 + 120 + 100 + 100)
=432/600
=72%
=432/600
=72%
Question 4 |

395 | |
455 | |
475 |
Question 5 Explanation:
Aggregate marks of sanya obtained in all five subjects
=0.9x150 + 0.6x130 + 0.85x120 + 0.8x100 + 0.6x100
=455
=0.9x150 + 0.6x130 + 0.85x120 + 0.8x100 + 0.6x100
=455
