The following table gives the percentage of marks obtained by seven students in six different subjects in an examination.

The Numbers in the Brackets give the Maximum Marks in Each Subject.

Student	Subject (Max. Marks)
	Maths	Chemistry	Physics	Geography	History	Computer Science
	(150)	(130)	(120)	(100)	(60)	(40)
Ayush	90	50	90	60	70	80
Aman	100	80	80	40	80	70
Sajal	90	60	70	70	90	70
Rohit	80	65	80	80	60	60
Muskan	80	65	85	95	50	90
Tanvi	70	75	65	85	40	60
Tarun	65	35	50	77	80	80

What was the aggregate of marks obtained by Sajal in all the six subjects?

409

419

429

449

Answer: Option

Explanation:

Aggregate marks obtained by Sajal

= [ (90% of 150) + (60% of 130) + (70% of 120)

+ (70% of 100) + (90% of 60) + (70% of 40) ]

= [ 135 + 78 + 84 + 70 + 54 + 28 ]

= 449.

90% of 150.

90% = 90/100 = 0.9.

= 0.9*150 = y.

Then y = 135.

Aggregate is 449, but we are not dividing it by 6. i.e 449/6.

Prathyusha said: 1 decade ago

Total marks 150 and obtained 90.

= (90/100)*150 = 135.

90% of 150 is 135? Could any one please explain?

Ketan sonar said: 7 years ago

10% of 150 = 15,
So, 90% of 150 = 15*9 = 135.
