*Directions to Solve*

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 |

5.

What is the overall percentage of Tarun?

Answer: Option

Explanation:

Aggregate marks obtained by Tarun

= [ (65% of 150) + (35% of 130) + (50% of 120)

+ ((77% of 100) + (80% of 60) + (80% of 40) ]

= [ 97.5 + 45.5 + 60 + 77 + 48 + 32 ]

= 360.

The maximum marks (of all the six subjects)

= (150 + 130 + 120 + 100 + 60 + 40)

= 600.

Overall percentage of Tarun = | 360 | x 100 | % = 60%. | ||

600 |

@David.

The question is overall percentage NOT overall marks, so you need to find the % overall.

In the above example 65% of 150 = 97.5. How it comes? Please explain.

For finding overall percentage in all the subjects for a particular person is there any shortcut method or trick?

Yes, @K.Niharika.

I also agree with you because answer will be 64.5.

Tarun's total is 387 hence 64.5%.

I too got the same value @Prashant.

The table is already in percentage so, why don't we sum up all the values and div by 6.

Total is 387/6=64.5%.

Why should we calculate the mark then have to find the average?

Correct me if I am wrong.

Each subject is weighted differently 60. In Math is not equal to 60. In History, Thus, you do have to calculate the marks, then compute the overall percentage.

You are right, Thanks @Kani.

@All.

Instead of average percentage, the overall percentage is asked here, so we have to divide the total obtained marks by total marks to calculate the overall percentage.
