There are 5 cocoa pods in a bag.

Virty [35]

Answer:

416 g

Step-by-step explanation:

The mean is calculated as

mean = $\frac{sum}{count}$ , then

$\frac{sum}{5}$ = 398 ( multiply both sides by 5 )

sum of 5 pods = 1990 g

let x be the weight of the sixth pod , then

$\frac{1990+x}{6}$ = 401 ( multiply both sides by 6 )

1990 + x = 2406 ( subtract 1990 from both sides )

x = 416

That is the weight of the sixth pod is 416 g
