ATQ, Let the future ages of Linda and Joan be 4x and 5x respectively, four years from now. The sum of their ages four years from now = 4x+5x = 9x. Four years ago, the sum of their ages = 56. Their combined ages today = 56+8 = 64. 9x = 64+8 = 72. Solving for x, 9x = 72 = x = 8 Age of Linda four years from now = 4x = 4×8 = 32 years. Current age of Linda = 32−4 = 28 years.
