Question

The average age of 6 members of a family is 45.5 years. If the age of a relative is also added, then new average becomes 47. The age of relative is? O 58 years O 56 years O 50 years 48 years​

Answer 1

Answer:

56

Step-by-step explanation:

Let the sum of ages of 6 members be x.

x / 6 = 45.5

x = 45.5 * 6

x = 273.

*When the age of a relative is added, then the number of members becomes 7*

Let the age of relative be y.

x + y / 7 = 47

x + y = 329

273 + y = 329

y = 56 years

Answer 2

Answer:

...

hence, the age of the relative is 56 years.
