Let scores of A, B and C are $$a,b$$ and $$c$$ respectively. According to ques, => $$a+b=120$$ --------------(i) $$b+c=130$$ --------------(ii) $$c+a=140$$ --------------(iii) Adding above equations, we get : $$2(a+b+c)=(120+130+140)$$ => $$a+b+c=frac{390}{2}=195$$ Substituting value from equation (i) in above equation, => $$120+c=195$$ => $$c=195-120=75$$ => Ans - (D)
