The difference of age between M and K = The difference of age between K and O. Sum of age of M and 0 = 100 years (M – K) = (K – O) M + O = 2 K Now, given that M + O = 100 Therefore, 100 = 2K K = 50 years Now, M – K =? Here, we know the value (age) of K is 50, but we do not know the age of M. ∴ (M – K) cannot be determined.
