A) 108
B) 132
C) 240
D) 360
Correct Answer: B
Solution :
Suppose, total marks of the examination is x. Then by question, \[\frac{x\times 45}{100}=80+280\] \[\Rightarrow \] \[\frac{45x}{100}=360\therefore x=\frac{360\times 100}{45}=800\] Now, minimum qualifying marks for Sita = 30% of \[800=\frac{30\times 800}{100}=240\] So, extra marks required by Sita to qualify the exam \[=240-108=132\]You need to login to perform this action.
