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.

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.
90% of 150 = 9 X (10%) = 15 x 9 = 135.

How you got 90% of 150=135?
Aishwarya said:

90% of 150.
90% = 90/100 = 0.9.
= 0.9*150 = y.
Then y = 135.
90% = 90/100 = 0.9.
= 0.9*150 = y.
Then y = 135.

Can't we find it in one step rather than firstly take out percentage then solve it out. Is there any way?

90% of 150, just calculate 10% of 150 i.e. 15 delete it from 135 you get.
90% of 150 as 135.
90% of 150 = 150-15 (15 is 10% of 150) = 135.
90% of 150 as 135.
90% of 150 = 150-15 (15 is 10% of 150) = 135.

Total marks 150 and obtained 90.
= (90/100)*150 = 135.
= (90/100)*150 = 135.
