Question

At an examination in which maximum marks are 500. P got 10% less than Q, Q got 25% more than R and R got 20% less than S. If P got 360 marks what percentage of marks was obtained by S ?

Answer 1

Given maximum marks = 500

P got $\frac{360}{500}\times 100=72$% as per question it is 90% of Q.

So $Q=\frac{72\times 100}{90}=80$%

which was 125% of R

so, $R=\frac{80\times 100}{125}=84$%

Which was 80% of S

So, $S=\frac{64\times 100}{80}=80$%

$\therefore$ S got 80% marks
