Given Data

 

 

Marks in Range Form                        Frequency of data
0-10 15
10-20 30
20-30 45
30-40 12
40-50 18

 

Maximum frequency in  given data is 45 lies in 20-30 Marks Range

So, mode surely exist in between 20 & 30

Mode = 20 + 10 imes frac(45-30)(45-30+45-12)

Mode = 20 + 10 imes frac(15)(48)

Mode = 20 +3.125

Mode = 23.125

Hence Mode is 23.125
