Vedclass · Answer

(D) The average age of the whole class is calculated using the formula: $	ext{Average} = \frac{	ext{Total sum of ages}}{	ext{Total number of students}}$.Let the number of boys be $n_b$ and the number of girls be $n_g$.The total age of boys is $16 	imes n_b$ and the total age of girls is $15 	imes n_g$.The average age of the whole class is $\frac{16n_b + 15n_g}{n_b + n_g}$.Since the ratio or the exact number of boys and girls is not provided,the weighted average cannot be determined.Therefore,the answer is that it cannot be computed with the given information.

The average age of the boys in a class is $16 \text{ years}$ and that of the girls is $15 \text{ years}$. The average age for the whole class is:
