Use Newton's 2nd law: a = (F - mg)/m. With g = 9.8 m/s^2:

- 10 kg, 60 N: a = (60 - 98)/10 = -3.8 m/s^2
- 10 kg, 40 N: a = (40 - 98)/10 = -5.8 m/s^2
- 20 kg, 60 N: a = (60 - 196)/20 = -7.0 m/s^2
- 20 kg, 40 N: a = (40 - 196)/20 = -8.0 m/s^2

The greatest (largest) acceleration is -3.8 m/s^2, so the 10 kg box lifted with 60 N.
