Here, the maximum frequency is 30 corresponding to class boundary 50 - 60

∴ f_m = 30, f₁ = 24, f₂ = 20, h = 10  and  L = 50

Mode	=	L	+	fm	-	f1			h
				2fm	-	f1	-	f2

Mode	=	50	+	30	-	24			10
				2(30)	-	24	-	20

Mode	=	50	+		6				10
				60	-	24	-	20

Mode	=	50	+		6				10

Mode = 50 + 3.75

Mode = 53.75 Packges.
