Answer:

The new mean is 77cm

Step-by-step explanation:

If the mean height of the 30 children in a room is 76 cm, then the sum of their ages is

$30 \times 76 = 2280cm$

If James with height 107cm joins them, then the total number of children now becomes 30+1=31 and the total height becomes: 2280cm+107cm=2387cm

The new mean now becomes:

$\bar x = \frac{2387}{31} = 77cm$
