Average of 67 values = 35
Adding 4 to each value = Mean (4) = 35x4 = 140
The new mean is 140.
Adding 4 to each value = Mean (4) = 35x4 = 140
The new mean is 140.

it's right?
Avg of 67 values is 35
this means that the total value is 67*35=2345
4 is added to each value. since there r 67 values, 4*67=268 is added.
2345+268=2613
the new avg=2613/67=39 right answer (Y)
