Vedclass · Answer

(A) Let the ages of Ina,Mina,and Dika be $I, M,$ and $D$ respectively.The average age is given by $\frac{I + M + D}{3} = x$.Therefore,the sum of their current ages is $I + M + D = 3x$.After $y$ years,each person's age will increase by $y$ years.The new sum of their ages will be $(I + y) + (M + y) + (D + y) = (I + M + D) + 3y$.Substituting the sum of current ages: $3x + 3y$.The new average age will be $\frac{3x + 3y}{3} = x + y$.

The average age of Ina,Mina,and Dika is $x$ years. After $y$ years,what will be their average age?
