Question

Four fifth of a number is more than three fourth of the number by 4. Find the number.

Answer 1

Answer:

x= 80

explanation

let number = x

given 4x/5 =3x/4 +4

4x/5=(3x+16)/4

by cross multiplying

4x*4=(3x+16)*5

16x=15x+80

16x-15x= 80

x= 80

Answer 2

Answer:

(4×4)x−(3×5)x20

=4

⇒16x−15x20

=4

⇒x20

=4.

Hence the value of x is 80.
