Question

24. Average age of three brothers is 25 years. If the age of two brothers 18 years and 27 years then find the age​

Answer 1

Answer:

30 years

Step-by-step explanation:

Let the age of third brother be x.

Average = (Sum of all numbers) / Total number of observations

=> 25 = (18+27+x) / 3

=> 25×3 = 45+x

=> 75 = 45+x

=> x = 75-45

=> x = 30
