19) The ages of A, B and C are 8 years 10 months,
15 years 6 months, 12 years 5 months respectively. What
is the average age of A, B and C?​

Answer 1

Answer:

12 year 3 months

Step-by-step explanation:

8 year = 8 × 12 months =96

the A age would be 96 + 10 = 106 months

15 year = 15×12 = 180 months

then B age would be = 180 + 6 = 186 months

12year = 12× 12 = 144 months

then C age would be = 144+ 5 = 149 months

Now average age would be = (106 +186+149)/3

= 441/3 = 147

Now 147 months = 147/12 years= 12 year 3 months
