Q30 of 37 Page 1

The following frequency distribution shows the distance (in metres) thrown by 68 students in a Javelin throw competition.


Draw a less than type Ogive for the given data and find the median distance thrown using this curve.

We need to make a less than type table first.



Since, N = 68


N/2 = 68/2 = 34


⇒ Draw a line parallel to x-axis where cumulative frequency is 34.


Clearly, line intersects at 36 on x-axis.


Thus, this is the point of median.


Hence, median = 36.

Two dairy owners A and B sell flavoured milk filled to capacity in mugs of negligible thickness, which are cylindrical in shape with a raised hemispherical bottom. The mugs are 14 cm high and have diameter of 7 cm as shown in given figure. Both A and B sell flavoured milk at the rate of ` 80 per litre. The dairy owner A uses the formula to π r2h find the volume of milk in the mug and charges ` 43.12 for it. The dairy owner B is of the view that the price of actual quantity of milk should be charged. What according to him should be the price of one mug of milk? Which value is exhibited by the dairy owner B? (Use π = 22/7)
