Step-by-step explanation:

Answer 2

The correct average would be 54 cm.

Step-by-step explanation:

Since we have given that

Average height of 5 kids = 60 cm

so, Sum of heights of 5 kids would be

$\dfrac{\sum x}{5}=60\\\\\sum x=60\times 5\\\\\sum x=300$

Now, one kid whose height was 45 cm was taken as 75 cm by mistake.

So, it becomes,

$\dfrac{300+45-75}{5}=\dfrac{300-30}{5}=\dfrac{270}{5}=54$

Hence, the correct average would be 54 cm.
