Answer:
Let
age of Aftab is represented by x
age of daughter is represented by y
Then Seven years ago,
age of Aftab = x -7
age of daughter = y-7
given that I was seven times as old as you were so we get
x - 7 = 7 ( y – 7 )
x – 7 = 7 y – 49
x- 7 y = - 49 + 7
x – 7 y = - 42 …(1)
x = 7 y – 42
plug y = 5,6 and 7 we get
x = 7 * 5 - 42 = 35 - 42 = - 7
x = 7 * 6 - 42 = 42 – 42 =0
x = 7 * 7 – 42 = 49 – 42 = 7
three years from now ,
Age of Aftab = x +3
Age of daughter = y+3
Given that I shall be three times as old as you will be so we get
x + 3 = 3 (y + 3)
x + 3 = 3 y + 9
x -3 y = 9- 3
x -3 y = 6 …(2)
x = 3 y + 6
plug y = -2,-1and 0 we get
x = 3 * - 2 + 6 = -6+6 =0
x = 3 * - 1 + 6 = -3+ 6 = 3
x = 3 * 0 + 6 = 0 + 6 = 6
