Question

⅔of a number is 20 less than the original number. Find the number. - 3 Four-fifths of a number is .​

Answer 1

Answer

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

Answer 2

Answer:

LET THE NUMBER BE x

A/Q

\begin{gathered} \frac{4}{5} x + 20 = x \\ \frac{4x + 100}{5} = x \\ 4x + 100 = 5x \\ 100 = x\end{gathered}

5

4

x+20=x

5

4x+100

=x

4x+100=5x

100=x
