The best answer would be:
given,
James 11 years
Julio 36 years
After some years Julio will be twice the age of James.
Julio = 2 * James.
consider year wise.
first,
Left hand side should be always >= to Right Hand Side
So,
consider the age after 10 years
add 10 on both sides:
Julio + 10 = 2 * (James + 10)
36 + 10= 2 * (11 + 10)
46 = 42
46 = 42 ( which is not equal to each other)
by this u can make out another 4 should be added on both side to make it LHS = RHS
36 + 14 = 2 * (11+14)
So after 14 years L.H.S = R.H.S
after 14 years the age of Julio will be twice the age of James.
