With this problem you need to calculate standard score and remember that the standard score should be the same with either population if it is really transformed from one population to another. The standard score is (please see the attached file).

For x = 74: 74 - 73/p = x_new - 10/2 => x_new = 92/9 = (please see the attached file)

For x = 60: 60 - 73/9 = x_new - 10/2 => x_new = 64/9 = ...
