Question

Four fifth of a number is greater than tree fourth of the numbers by 4​

Answer 1

Answer:

The number is 80

Step-by-step explanation:

Let the required number be 'x', then four-fifths of the number =  4/5x

And three - fourths of the number =  3/4x

It is given that    4/5x is greater than   3/4x  by 4

⇒   4/5x -3/4x = 4

⇒ 16x−15x /20 = 4

⇒ x/20 =4

⇒   x=4x20 ⇒ x=80

hence the required number is 80.
