Consider mass A, B and C as one object
Use formula
Net force = ma
      Weight-friction  = ma
(1+1)g -4 = (1+1+1)a
        16 = 3a
         a = 5.33 ms^-2

Consider mass A
T1-4 = ma
T1 = 4+5.33 = 9.33N

Consider mass C
mg - T2 = ma
10-T2= 5.33
T2 = 4.67 N

This is the fastest method but not good for your understanding
