Question

25% of so = 250, find x. ​

Answer 1

Answer:

25/100*x=250

=1/4*x=250

=x=250*4

X=1000

Answer 2

Correct question is "25% of x = 250,find x."

Answer:

Required value of x is 1000.

Step-by-step explanation:

Given, 25% of x = 250.

We know, a% of b $= \frac{a}{100} \times b$

So,

$25\% \: of \: x = 250 \\ \frac{25}{100} \times x = 250 \\ \frac{x}{4} = 250 \\ x = 250 \times 4 \\ x = 1000$

Required value of x is 1000.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
