Let the number is x

Now going with the statement of the question

20% of 40% of x is 10 greater than half of x

So

\frac{20}{100} (\frac{40}{100} (x)) = \frac{x}{2}+10

\frac{800}{10000} *x = \frac{x}{2} +10

\frac{8}{100} x = \frac{x}{2} +10

Subtract \frac{x}{2} from both sides

\frac{8}{100} x - \frac{x}{2} =10

\frac{8x}{100}  - \frac{50x}{100} =10

\frac{-42x}{100}=10

Multiply 100 on both sides

-42x = 1000

Divide both sides by -42

x=\frac{-500}{21}
