5) None of these

10.Who has secured 60% marks in Physics?
1) Shreya
2) Arpita
3) Geetanjali

1. 5
Since, Time Period is not given, So we cannot find.

2. 4
We can find the expenditure of a person using any two statements

3. 1
Area of IIgm = Area of two triangles
Area of triangle = √(s(s-a)(s-b)(s-c) )

4. 3
Let the speed of bus be ‘b’ and train be ‘t’
Distance = d
From statement A,
d/b+d/t=15 hrs
From statement C,
2d/t=15-3=12
d/t=6
So, 2d/b = (15-6)*2 = 18 kmph

5. 4
In radius = Area of triangle/semi perimeter

6. 4
Required % = (45*100)/75 = 60%

7. 5
Total marks obtained by Shreya = 348
Total marks od paper = 515
Required % = 348*100/515 = 67.5%

8. 1
Total marks of Mehra = 347
Total marks of Shreya = 348
Total marks of Geetanjali = 383
Total marks of Rishab = 343
Total marks of Arpita = 353
Total marks of Prashat = 360

9. 3
Required ratio = 56 : 84
= 2 : 3

10. 4
60% of 75 = 45
So, Answer is Rishab
