Answer :

GIVEN:


FORMULA USED:


Mean =


Median =


Mode = Maximum number of terms


Let ages of employees be x


And number of person be frequency (f)



For Mean:


Mean =


∑xf = 247 + 315 + 460 + 450 + 432 + 493 + 403


= 2800


∑f = 13 + 15 + 20 + 18 + 16 + 17 + 13


= 112


Mean = = 25


For Median


Total frequency (N) = ∑f = 112


N/2 = = 56


Which lies in commutative frequency 66


Which is having value of x to be 25


Median = 25


For Mode


Maximum number of terms(f) in above table is 20


20 terms are of value 23


Mode = 23


CONCLUSION: The data is having Mean to be 25


Mode to be 23


Median to be 25
