Question

If the mean of p,q,r,s and t is 5 find the value of (p - 5) + (q - 5 )+(r- 5) + (s - 5) + (t- 5) is

Answer 1

SOLUTION

GIVEN

The mean of p,q,r,s and t is 5

TO DETERMINE

The value of

(p - 5) + (q - 5 )+(r- 5) + (s - 5) + (t- 5)

EVALUATION

Here it is given that the mean of p,q,r,s and t is 5

So by the given condition

$\displaystyle \sf{ \frac{p + q + r + s + t}{5} = 5 }$

$\displaystyle \sf{ \implies p + q + r + s + t= 5 \times 5 }$

$\displaystyle \sf{ \implies p + q + r + s + t= 25 }$

Now

(p - 5) + (q - 5 )+(r- 5) + (s - 5) + (t- 5)

= p + q + r + s + t - 25

= 25 - 25

= 0
