its simple 5.90
Step-by-step explanation:
Total age of pupils
= 12.7 x 10
= 127 years
127 - 11 - 10 - 12 - 11 - 14 - 13 - 14 - 16 = 26 ( total age of the other 2 pupils added together )
however, since the ninth pupil is two years younger,
26-2=24
24/2=12 ( age of ninth pupil )
12+2=14 ( age of tenth pupil )
thus, (a) 12 years old,
(b) 14 years old.
