Question

a student secure 90% 60% and 54% marks in 3 test paper with maximum marks hundred 150 200 respectively find his aggregate percentage​

Answer 1

Step-by-step explanation:

A student secures 90% , 60% and 54% marks in test papers with 100, 150, 200 respectively as maximum marks.

Now, 90% of 100 = 0.90 × 100

                             = 90

60% of 150 = 0.60 × 150

                   = 90

54% of 200 = 0.54 × 200

                    = 108

Total marks obtained in the test = 90 + 90 + 108

                                                      = 288

Total maximum marks which can be obtained = 100 + 150 + 200

                                                                             = 450

So, Aggregate Percentage of Marks = 288/450 × 100

                                                               = 64%
