$<u>Your Question -</u>$

40% of a number is 800. Find the number.

$<u>Solution -</u>$

Let the number be 'x'.

Then, 40% of x
= 40/100 × x
= 40x/100

But, 40% of x = 800 (as given in the question)

Then,

40x/100 = 800

=> 40x = 800 × 100

=> 40x = 80000

=> x = 80000/40

=> x = 2000

Answer 2

Step-by-step explanation:

$let \: the \: number \: be\: x \\ \\ 40\% \: of \: x = 800 \\ \\ {i.e} \frac{40 \times x}{100} = 800 \\ \\ x = \frac{800 \times 100}{40} \\ \\ \\ x = 2000........ \\ \\ \\ \\ \\ \\ \\ \\ therefore \: the \: requried \: number = 2000$

hope this helped you
