Given that the average age of three children in the family is 25% of the average of the father and the eldest child Therefore, let us suppose the age of the three children be a, b , c And the average would be = (a+b+c)/3 = 25/100×(28+c)/2 = (a+b+c)/3 = (28+c)/8……………..(i) Let us suppose that the age of mother is d, ∴ d + a = 49 …………………(ii) Even from both the equations, value of b cannot be determined.
