Answer:

Answer:

d) 27 years

Step-by-step explanation:

First we have to do that the TOTAL sum of the AGE of 15 students =

15 \times 1815×18

=270

the total sum of the age of 9 students =

9 \times 129×12

=108

the average age of the 6 students =

\begin{gathered}(270 - 108) \div 6 \\ = 162 \div 6 \\ = 27\end{gathered}

(270−108)÷6

=162÷6

=27
