Question

The average ages of three persons 27 years. Their ages are in the proportion of 1:3:5. what is the age in years of the youngest one among them ?​

Answer 1

1+3+5 = 9 27 divided by 9 = 3 Age 1 = 3. Age 2 = 9. Age 3 = 15

Answer 2

Answer:

9 years old

Step-by-step explanation:

the average age of 3 people is 27

x / 3 = 27.....x = 27 * 3.....x = 81......this means that the total of their ages is 81.

their ages are in the proportion of 1:3:5....added = 9

this means that the first person is 1/9 of the total ages..

the second person is 3/9 of the total ages

the third person is 5/9 of the total ages

person 1 : 1/9 of 81 = 81/9 = 9 years old <==== this is the youngest

person 2 : 3/9 of 81 = 243/9 = 27 years old

person 3 : 5/9 of 81 = 405/9 = 45 years old
