Answer:

85

Step-by-step explanation:

Wages per day                     No.of workers             fₓ

(x)                                                (f)

50                                               2                              100  

60                                               4                               240

70                                                8                              560

80                                                12                            960

90                                                10                            900

100                                               6                             600

110                                                8                             880

                                                   ---                             -------

                                                   50                            4240

∴ Mean = ∑fₓ/∑f

             = 4240/50

             = 84.8

             = ~85.

Second part:

Given that the number of workers is doubled.

Mean remains the same = 85.

Hope it helps!


wwwalison8888a: But why does the mean remains the same?
siddhartharao77: In this the number of workers are doubled not their wages!
