Question

Q31. Of the three friends, second friend is twice as old as the first and is also thrice as old as the third. If the average age of the three is 44, find the age of oldest person.

• A. (a) 42
• B. (b) 63
• C. (c) 66
• D. (d) 90

Answer 1

The correct option is C

(c) 66

Let age of Ist person = x

Then second person’s age = 2x and third person’s age = 3x

$\frac{x+2x+3x}{3}=44\frac{6x}{3}=44X=\frac{44x3}{6}$

X = 22

Age of oldest person is = 3x

= 3 × 22 = 66 years
