We are here given by the average age of three children in a family is 35% of the average of 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 = 35/100×(28+c)/2 = (a+b+c)/3 = (32+c)/8……………..(i) Let us suppose that the age of mother is b, So given condition that the b + a = 43. But from this we cannot determined the value of b .
