Question

four fifth of a number is greater than three fourth of a number by 4 what is the answer​

Answer 1

Let the required number be 'x', then four fifths of the number =54x

And three fourths of the number =43x

It is given that 54x is greater than 43x by 4

⇒ 54x−43x=4

2016x−15x=4

⇒ 20x=4 ⇒ x=80

hence the required number is 80.
