The following table shows the marks of four students in four different subjects in an examination. Who among the four students scored the lowest aggregate marks, when marks obtained in all the four subjects were taken together?

R

Total marks of P = 65 + 75 + 72 + 58 = 270

Total marks of Q = 73 + 67 + 78 + 52 = 270

Total marks of R = 71 + 59 + 55 + 65 = 250

Total marks of S = 57 + 73 + 58 + 71 = 259

So , Lowest aggregate marks is of S .
