Muskan | 80 | 65 | 85 | 95 | 50 | 90 |
Tanvi | 70 | 75 | 65 | 85 | 40 | 60 |
Tarun | 65 | 35 | 50 | 77 | 80 | 80 |
3.
What was the aggregate of marks obtained by Sajal in all the six subjects?
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.

(90/100) * 150 = 135.

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

90 is not the percentage obtained by Sajal in Maths. 90 is the total mark obtained by him in Maths out of 150. i.e. He scored only 60% for Maths. Then how come we take 90% of 150?

@Karthika.
There is a difference between aggregate and average.
Hope you can understand it.

@Renu.
If they ask aggregate we should divide 449 by 6.
Here only aggregate marks are asked.

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

10% of 150 = 15.
90% of 150 = 9 X (10%) = 15 x 9 = 135.
Similarly find 10% of total and multiply as required.

Aggregate marks are given already then what the need to calculate %.
Why can't we directly sum up the given marks?
