13 years back my father’s age was triple of my brother’s age. Five years from now my father will be twice as old as my brother. Find my age now if I am twice of my brother’s age.

If the current age is x, then age n years later = x+n. If the current age is x, then age n years ago = x – n. The ages in a ratio a : b will be ax and bx. If the current age is x, then 1 /n of the age is x/n. If you assume the current age to be x, then the age after n years will be (x+n) years. If you assume the current age to be x, then the age before n years will be (x-n) years. If the age is given in the form of a ratio, for example, p:q, then the age shall be considered as qx and px If you assume the current age to be x, then n times the current age will be (x×n) years If you assume...
