The average age of seven members of a family is 35 years. If one member aged 35 years is not included, the ages of the other six members are in the ratio 1:2:3:4:5:6. Find the age of the eldest member of the family.

A60 years ✓ Correct

B65 years

C61 years

D58 years

Correct answer: (A) 60 years

Explanation

The eldest member is 60 years old.

seven members total = 7 x 35 = 245.

removing the 35 year old leaves 245 - 35 = 210.

ratio parts 1+2+3+4+5+6 = 21.

one part = 210 / 21 = 10.

eldest = 6 x 10 = 60 years.
