Question

Ajay gets 20% less marks than that of Vatsal's marks. By what percent Vatsal's marks are more than Ajay's marks ?

Answer 1

let the marks of vatsal be 100x
so the marks of ajay= 80x
difference in marks= 20x
so percentage by which vatsals mark are more= (20x/80x)*100= 25%

Answer 2

Let Vatsal's marks be 100x

then Ajay's marks = 100x - 20x = 80x

Difference of Vatsal's and Ajay's marks =100x - 80x  = 20x

 ∴ percent Vatsal's marks are more than Ajay's marks = 20x/80x *100 = 25%
