Ravish tells his daughter Aarushi, “Seven years ago, I was seven times as old as you were then. Also, three years from now, I shall be three times as old as you will be”. If present ages of Aarushi and Ravish are x and y years respectively, represent this situation algebraically as well as graphically.

Answer 1

It is given that seven year ago Harish was seven times a sold as his daughter 

It is also given that after three years from now Ravish shall be three times a sold as her daughter

Thus, we have following table for the points on the Line 7x -42 = y

We have

Thus, we have following table for the points on the Line y = 3x +6
