In Maths percentage $=\frac{120}{150}\times 100$

$=\frac{4}{5}\times 100=80\mathrm{\%}$

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

Hence, Overall % $=\frac{364}{500}\times 100=\frac{364}{5}=72.8\mathrm{\%}$
