Question

In an examination, Kavita scored 120 out of 150 in Maths, 136 out of 200 in English and 108 out of 150 in Science. Find her percentage score in each subject and also on the whole (aggregate).

Answer 1

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