Question

2 by 3 of a number is 20 less than the original number. find the number ?​

Answer 1

Answer:

60

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

hope it helps!!

Answer 2

Answer:

(2/3)x = x - 20

Clear the fraction by multiplying through by 3

2x = 3x - 60

60 = 3x - 2x

x = 60
