Dear Student,

Please find below the solution to the asked query:

We have  :
Classes 0 - 5 5- 10 10 -15 15- 20 20 -25
Frequency 7 6 f 4 3

And modal class is below ( 10 - 15 ) 

We know : The group with the highest frequency is called modal class .

So, Height frequency below ( 10 - 15 ) so , We get modal class ( 0 - 5 ) as 7 > 6 ,

Therefore,

f < 7

Option ( D )                                                                ( Ans )
