Question

2/3 of a number 20 less then original number find the number​

Answer 1

Step-by-step explanation:

Let the original number be x.

According to the question we can write as (2/3)x+20x

On rearranging x−(2/3)x=20

Now taking the L.C.M od 1 and 3 is 3

(3x−2x)/3=20

x/3=20

Again by transposing x=60

So the original number is 60

Let the number=x

2/3of x-20=x

2/3x-20=x

2/3x-x=20

2x-x=20×(-3)

x=-60
