Answer 1

$\huge {\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

(i) In english her performance is worst.

(ii) In mathematics her performance is the best.

(iii) Aggregate percentage = 0.756%

Step-by-step explanation:

Mark scored in science = 60/75

Mark scored in mathematics = 84/100

Mark scored in hindi = 36/50

Mark scored in english = 30/45

% of science mark = 60/75 × 100 = 80%

% of mathematics mark = 84/100 × 100 = 84%

% of hindi mark = 36/50 × 100 = 72%

% of english mark = 30/45 × 100 = 66.6%

(i) In english her performance is worst.

(ii) In mathematics her performance is the best.

(iii) Aggregate percentage = % of all subjects mark scored by Preeti/% of all subject.

Aggregate percentage = 80 + 84 + 72 + 66.6 / 100 + 100 + 100 + 100

= 302.6/400 %

= 0.756%
