Madhya Pradesh Police Exam Model Paper 6

Given:
Marks of Gopal = Marks of Dhiraj + 280
Marks of Dhiraj + 120 = 60% increase in the marks of Dhiraj
Calculation:
Let the marks of Dhiraj be x.
Marks of Dhiraj + 120 = 60% increase in the marks of Dhiraj
$\Rightarrow \mathit{x}+120=\mathit{x}+0.6\mathit{x}$
$\Rightarrow 0.6\mathit{x}=120$
$\Rightarrow \mathit{x}=200$
Marks of Gopal $=200+280=480$
∴ The marks of Gopal is 480.
