Question

Let a, b , c ,d , p be 5 real number and their Arithmetic mean be 2 . If arithmetic mean of a,b,c,d is 4 then the possible value of 'p' is

Open in App

Solution

$\begin{matrix} \frac{a + b + c + d + p}{5} = 2 a + b + c + d + p = 10........ (1) G i v e n, \frac{a + b + c + d}{4} = 4 a + b + c + d = 16....... (2) s u b t r a c t i n (1) H e n c e, p = - 6 \end{matrix}$
