| In a test, Rajesh got 112 marks which is 32 more than the passing marks. Sonal got 75% marks which is 70 more than the passing marks. What is' the minimum passing percentage of the test? |
A) 35%
B) 45%
C) 40%
D) 30%
Correct Answer: C
Solution :
| \[\because \]Passing marks of test \[=112-32=80\] |
| Now, let total marks \[=x\] |
| \[\therefore \]75% of \[x=80+70\] |
| \[\Rightarrow \] \[\frac{75\times x}{100}=150\] |
| \[\Rightarrow \] \[x=\frac{150\times 100}{75}\]\[\Rightarrow \]\[x=200\] |
| \[\therefore \]Passing percentage \[=\frac{80}{200}\times 100=40%\] |
