Vedclass · Answer

(A) Let the present ages of Sachin and Sehwag be $S$ and $W$ respectively.According to the problem,after $x$ years,the sum of their ages will be $y$ years.So,$(S + x) + (W + x) = y$.$S + W + 2x = y$.Therefore,the present sum of their ages is $S + W = y - 2x$.We need to find the sum of their ages $3$ years ago.Sum of ages $3$ years ago $= (S - 3) + (W - 3) = (S + W) - 6$.Substituting the value of $(S + W)$,we get $(y - 2x) - 6 = y - 2x - 6$ years.

After $x$ years,the sum of the ages of Sachin and Sehwag will be $y$ years,then the sum of the ages before $3$ years was $\ldots \ldots \ldots \ldots$ years.
