“Four years ago the older brother’s age was five times of the younger brother’s age. If currently the older brother’s age is three times of the younger brother’s age, how old is the older brother in ten years from now?
The answer is, yes true, the answer is: I Don’t Know.
Because one’s life time age, only God knows it.
Maths is easy and pleasant, isn’t it? Isn’t!”
