Answer 1

diana = 43
mama=28 + a = x
tata = 22 + b = x
alin=27 + c = x 
a+b+c=43

28+22+27+(a+b+c)=3x
77 + 43 = 3x
3x=120
x=40               tata primeste : b= x-22=40-22=18  
                       mama primeste : a =x-28=40-28=12
                       alin primeste : c=x-27=40-27=13

18+12+13=43 mere are Diana
