The average age of 5 member of a family is 25 yr. If the servant of the family is included the average age increased by 40% .What is the age of servant?
-
- 85 yr
- 90 yr
- 73 yr
- 55 yr
Correct Option: A
Total age of 5 members = 25 x 5 = 125 yr
Total age of 5 member and the servant
= (25 + 25 x 40/100) x 6
= 35 x 6 = 210 yr
∴ Age of the servant = 210 - 125 = 85 yr
