| How come max marks in his and comp is low and students have scored more marks? | |
| Bhavhar said: (Mar 1, 2014) | |
| Is there any shortcut for these type of sums? I mean here the percentage calculation is easy but say for eg. If the percentage of sajal is 68% in maths, 73%in history and so on then what should we do? |

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

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

| 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. |

| Can't we find it in one step rather than firstly take out percentage then solve it out. Is there any way? | |
| Aishwarya said: (Aug 24, 2015) | |
| 90% of 150. 90% = 90/100 = 0.9. = 0.9*150 = y. Then y = 135. |

| Aggregate marks are given already then what the need to calculate %. Why can't we directly sum up the given marks? |
|
| D D said: (Nov 7, 2015) | |
| 10% of 150 = 15. 90% of 150 = 9 X (10%) = 15 x 9 = 135. Similarly find 10% of total and multiply as required. |

| Aggregate is 449, but we are not dividing it by 6. i.e 449/6. | |
| Karthika said: (Apr 23, 2016) | |
| @Renu. If they ask aggregate we should divide 449 by 6. Here only aggregate marks are asked. |
|
| Shadab Akhtar said: (May 4, 2016) | |
| @Karthika. There is a difference between aggregate and average. Hope you can understand it. |

| 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? | |

| Awesome learning ways. Thank you all. | |

| Not understanding this, please someone explain me. | |
| Ketan Sonar said: (Jun 21, 2018) | |
| 10% of 150 = 15, So, 90% of 150 = 15*9 = 135. |

| (90/100) * 150 = 135. | |
