Answer» Step-by-step explanation: Let the present age of son = X years Therefore, Present age of FATHER = 3x years 5 years ago: Son's age = x - 5 Father's age = 3x - 5 According to the given information: 3x-5= 4(x - 5) 3x - 5 = 4x - 20 20 - 5 = 4x - 3x 15 = x Therefore, 3x = 3 * 15 = 45 Thus, Son's present age = 15 years Father's present age = 45 years |
