Questions 1-4

1..

*(e)*: Aggregate marks obtained by Sajal
= [(90% of 150) + (60% of 130) +
(70% of 120) + (70% of 100) +

(90% of 60) + (70% of 40)] = 135
+ 78 + 84 + 70 + 54 + 28 = 449.

2.

*(c)*: Aggregate marks obtained by Tarun .
= [(65% of 150) + (35% of 130) +
(50% of 120) + (77% of 100) + (80% of

60) + (80% of 40)] = 97.5 + 45.5
+ 60 + 77 + 48 + 32 = 360.

Total maximum marks (of all the
six subjects)

= (150 + 130 + 120 + 100 + 60 +
40) = 600.

Overall percentage of Tarun = 360
x 100 % = 60%.

. 600

3.

*(b)*: Average marks obtained in Physics by all the seven students
= 1 [(90% of 120) + (80% of 120)
+ (70% of 120) + (80% of 120)

7

+ (85% of 120) + (65% of 120) +
(50% of 120)]

= 1 [(90 + 80 + 70 +80 + 85 + 65
+ 50)% of 120]
