Answer:

In the question cumulative frequency is given that is why it is converted into frequency

class. fi

0-10. 3

10-20. 8-3=5

20-30. 17-8= 9

30-40. 20-17= 3

40-50. 22-20= 2

Now here modal class is 9

therefore l = 20 , F1=9 , f0 = 5, F2 = 3 , h 10

By formula

Mode = l + (f1-f0/ 2f1 - f0 - F2)× h

= 20 + (9-5/18-5-3)×10

= 20 + 40/10

= 20 + 4

= 24

Therefore the mode is 24 of the given question
