Question

9 Lalit got 50% marks in Hindi, 75% in English, and 90 marks
in maths. The maximum marks in each of the subjects were 100, 140,
and 160 respectively. Find his aggregate percentage.​

Answer 1

Hindi = $100 \times \frac{50}{100} = 50$ marks out of 100 marks

English $=140 \times 75/100$ = 105 marks out of 140 marks

Maths, 90 marks out of 160 marks

Aggregate % = obtained marks/ total marks *100

$(50+105+90)/(100+140+160) \times 100 \\ = \frac{245}{400} \times 100 = 61.25 \%$

Answer 2

Answer:

Hindi, 100*50/100 = 50 marks out of 100 marks

English, 140*75/100 = 105 marks out of 140 marks

Maths, 90 marks out of 160 marks

Aggregate % = obtained marks/ total marks *100

= (50+105+90)/(100+140+160)*100 =245/400*100 = 61.25 %
