In a competitive exam, Ram got 10% less than Shyam who got 25% more than Mohan and Mohan got 20% less than Jawa. If the total marks were 500 and Ram got 360.What was Javas percentage?
80
64
72
None of these
Explanation:
Given, marks of Ram = 360.
Then, according to the given data,
=> 360 = 90% of Shyam
=> Shyam = 360 * 10 /9 = 400
And, Shyam = 125% of Mohan
=> 400 = 125/100 $\times$ Mohan
=> Mohan = 400 $\times$ 100/125 =80 $\times$ 4= 320
Mohan = 80% of Java.
=> 320 = 80/100 $\times$ Java
=> Java = 320 $\times$ 100 / 80 = 400
Therefore, Javas percentage = 400/500 $\times$ 100 = 80%.
