Answer 2

Question:

The average age of 6 servants in my house is 28 years. A new servant replace on old servant, then the new average age reduce by 1 year. The age of new servant is_?

(a) 26 years old

(b) 22 years old

(c) 35 years old

(d) Cannot be determined

Given:

Average age of 6 servants = 28 years old

A new servant replaced an old servant.

The new age is reduced by 1 years old.

To Find:

The age of the new servant.

Solution

Find the total age of the 6 servants (with the old servant):

Average age = 28 years old

Total age = 28 x 6

Total age = 168 years

Find the total age of the 6 servants (with the new servant):

Average age = 28 - 1

Average age = 27 years old

Total age = 27 x 6

Total age = 162 years

Find the difference in the total:

Difference = 168 - 162

Difference = 6 years old

Conclusion:

The age of the new servant cannot be determined because we do not know the age of the old servant that he was replacing. But we do know that the new servant is 6 years younger than him.

Answer: (d) Cannot be determined.
