Question

Lalit got 50% marks in hindi 75 % in english and 90 marks in maths .the max marks in each of the subject were 100,140,and 160 .find his aggregate parcentage

Answer 1

Marks scored in Hindi = 50%
Maximum marks in Hindi = 100
So, Marks scored in Hindi = 50% x 100
                                          = 50/100 x 100
                                          = 50
Marks scored in English = 75%
Maximum marks in English = 140
So, Marks scored in English = 75% x 140
                                              = 75/100 x 140
                                              = 105
Marks scored in Maths = 90
Maximum marks in Maths = 160
Total marks obtained in all subjects = 50 + 105 + 90
                                                         = 245
Maximum marks of all subjects = 100 + 140 + 160
                                                  = 400
Aggregate percentage = 245/400 x 100%
Aggregate percentage = 61.25%
This is the required answer.
Thanks.

Answer 2

Solution :-

Marks scored in Hindi = 50 %
Maximum marks = 100

Marks scored in Hindi = (100*50)100 

Marks in Hindi = 50

Marks scored in English = 75 %
Maximum marks = 140

Marks scored in English = (140*75)100

Marks in English = 105

Marks scored in Maths = 90
Maximum marks = 160

Total marks scored in Hindi, English and Maths = 50 + 105 + 90

= 245

Maximum marks in all subjects = 100 + 140 + 160

= 400

Aggregate percentage = (245*100)400

= 24500/400

= 61.25 %
