Answer:
(i)Hindi
(ii)30 marks more in Mathematics than Hindi.
(iii)No.
Step-by-step explanation:
(i) 540 students in 360°
1 student in (360/540)°=2/3°
105 students in (2/3×105)°=70°
In 70° there is Hindi.
(ii) We know that in Hindi the marks scored was 105.
Now in maths the marks scored was -
We know that 90° is (90/360)=1/4 part of 360°
so, if 360°=540 marks then
90°=(540×1/4)=135 marks.
Therefore, the student scored (135-105) marks=
30 marks more in math than hindi.
(iii) In this question we don't need to calculate the marks obtained in each subject, rather we can find it out by adding up the degree of the given subjects.
(Social Science + Mathematics)°=155°
(Science + Hindi)°=150°
Therefore, the sum of the marks obtained in Social Science and Mathematics is not greater
than the sum of marks obtained in Science and Hindi.
