Arjun scored 66 out of 75 in science and 46 out of 50 in mathematics, in which subject did he perform better?

Hi Syed!!
Here Is The Answer:

Marks Of Arjun In Science =>   66  
                                                    75

Marks Of Arjun In Mathematics =>   46  
                                                            50

L.C.M Of 75 & 50 => 150

Marks In Science =>    66   x   2   =>   132  
                                      75        2           150

Marks In Mathematics =>   46   x   3   =>   138  
                                             50        3            150

Since 138 > 132,
He Performed Better In  Mathematics .

Hope It Helps You!!!
