Question

Anubhavs marks are 20% less than Abhisheks marks .by what per cent are Abhisheks marks more the Anubhav marks

Answer 1

Abhishek's marks = x
Anubhav's marks = x - (20% of x)
                            = x - 0.2x
                            =0.8 x
difference in marks = x - 0.8x = 0.2 x
Abhishek's marks is more than by Anubhav's marks by

[difference/(Anubhav's marks)]×100
= (0.2/0.8)×100
=25%

Answer 2

Answer:

let Abhishek marks be x

so,anubhav marks =x-(20% of x)

x-(x×20/100)

x-(x×2/10)

x-(x×0.2)

x-0.2x

x-2x/10

(10x-2x)/10

8x/10

0.8x

Abhishek marks more than anubhav marks

=Abhishek marks- anubhav marks /anubhav marks × 100

=x- 0.8 x/0.8x× 100

=0.2 x / 0.8 x × 100

=1/4×100

=100/4

=20%
