Number of students 1 2 4 15 15 25 15 10 2 1

Find the modal marks.


The mode of a distribution is 55 and the modal class is 45-60 and the frequency preceding the modal class is 5 and the frequency after the modal class is 10. Find the frequency of the modal class.

Section C

11. How many terms of the Arithmetic Progression 45, 39, 33, … must be taken so that their sum is 180? Explain the double answer.

12. Draw a circle of radius 3 cm. From a point P, 7 cm away from centre draw two tangents to the circle. Measure the length of each tangent.


Draw a circle of radius of 3 cm. Take two points P and Q one of its diameter extended on both sides, each at a distance of 7 cm on opposite sides of its centre. Draw tangents to the circle from these two points.

13. Fencing a Backyard : Tina and Shriya have just purchased a purebred German Shepherd, and need to fence in their backyard so the dog can run.

(i) What is the maximum rectangular area they can enclose with 200 ft of fencing, if they use fencing material along all four sides? What are the dimensions of the rectangle?

(ii) What is the maximum area if they use the house as one of the sides? What are the dimensions of this rectangle?

14. Silo : A silo is a structure for storing bulk materials. Silos are used in agriculture to store grain or fermented feed known as silage. Silos are commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust.

A silo is in the shape of cylinder surmounted by a conical top. The height and diameter of cylindrical part are 40 feet and 42 feet respectively and the slant height of conical part is 29 feet.
(i) How much metal sheet is required to make this silo ?
(ii) What is the storage capacity of silo ?
