hey mate here is your answer :

c.i

0-10

10-20

20-30

30-40

40-50

50-60

frequency :

0

18

20

15

7

5

here highest number in the frequency = 20 = f1

f2 = 15 , f0 = 18 , l ( lower limit ) = 30 ( f1 opposite side = 20-30 ) , h ( height ) = 10

the formula of mode =

l + f1-f0

2×f1-f0-f2×h
