7. 
   

   Area of square = l² = 5² = 25

   Area of rhombus = base ´ height = 5 ´ h

   But in right angled D PST, the side PT is less than the hypotenuses PS

   i.e. PT < PS

   i.e. h < 5

   \ 5 ´ h < 5 ´ 5

   \ Area of rhombus < Area of square

   Hence A.

8. The roots of the quadratic equation x² - 12 x + 35 = 0 are 5 and 7.

   Hence product = 35 and sum = 12

   Hence product > sum

   Hence A.

9. 

   Hence A.

   (Note : A very large number of students when dividing 1212 by 12 will not take into account the zero in 101 and write the answer wrongly as 11 ).

   
   
10. .11 + 9.01 + 10.87359          20

    In column A, the whole numbers 10 and 9 add up to 19. Hence only the sum of the decimal parts need to be compared with 1.

    Now 0.11 + 0.01 = 0.12 which when added to 0.88 will give one.

    But 0.87359 is less than 0.88

    Hence A < B

    Hence B.
