Let the number be x

We are given that 20/3 of a number is subtracted from itself then the result becomes 5670

So, x-\frac{20}{3}x=5670x−

20

x=5670

\frac{3-20}{3}x=5670

3

3−20

x=5670

\frac{-17}{3}x=5670

3

−17

x=5670

x=5670 \times \frac{3}{17}x=5670×

x=\frac{-17010}{17}x=

17

−17010

Hence the original number is \frac{-17010}{17}

−17010
