In an examination, Kavita scored 120 out of 150 in Maths, 136 out of 200 in English and 108 out of 150 in Science. Determine her percentage score in each subject as well as overall (aggregate).

Marissa Snow

In Maths percentage $=\frac{120}{150}×100$
$=\frac{4}{5}×100=80\mathrm{%}$
In English percentage $=\frac{136}{200}×100=\frac{136}{2}$
= 68%
In Science percentage $=\frac{108}{150}×100=\frac{108×2}{3}$
= 72%
Total number scored = 120+136+108 = 364
Maximum marks = 150+200+150 = 500
Hence, Overall % $=\frac{364}{500}×100=\frac{364}{5}=72.8\mathrm{%}$
