Question

The mean of a, b, cand d is 12. What will be the mean of a, b, c, d and e if e = 50?​

Answer 1

Answer:

$\frac{98}{5}$ or 19 $\frac{3}{5}$

Step-by-step explanation:

We already know mean of a, b, c, and d = 12

Let [a, b, c, d] = A

If mean = 12, A = 12 * 4 = 48

Therefore, if we add a, b, c, and d, we get 48

Now, e = 50

Therefore, let's find the mean

= $\frac{a + b + c + d + e}{5}$

= $\frac{A + e}{5}$

= $\frac{48 + 50}{5}$

= $\frac{98}{5}$ or 19 $\frac{3}{5}$
