A says, "if you reverse my own age, the figures represent my brother's age. He is, of course, senior to me and the difference between our ages is one - eleventh of the sum of our age." Then A's brother's age is?
Answer & explanation
Correct answer: option 2
Check by answer option (2) → 54
A'a age = 45 years
A's bother age = 54 years
Difference of their age = 54 - 45 = 9 years .... (i)
Sum of their age = 54 + 45 = 99
ATQ,
⇒ Difference of their age = 99 × \(\frac{1}{11}\) = 9 years .... (ii)
(i) and (ii) are same. Hence, 54 years is age of A's brother.
