Answer 1

Question :

Q) find x , if mean of x+1 , x+2 , 2x+1 , x+3 and x-2 is 12?

Answer:

Given:

• (x+1) , (x+2) , (x+3) , (2x+1) , (x-2) are numbers
• mean of these numbers = 12

To Find:

• value of x

Answer:

we know that ,

$\implies$$mean = \frac{sum \: of \: numbers}{total \: number \: of \: numbers}$

$\implies$$\frac{(x + 1) + (x + 2) + (x + 3) + (2x + 1) + (x - 2) }{5} = 12$

$\implies$$\frac{x + 1 + x + 2 + x + 3 + 2x + 1 + x - 2}{5} = 12$

$\implies$$6x + 5 = 12 \times 5$

$\implies$$6x = 60 - 5$

$\longrightarrow$$x = \frac{55}{6}$
