Let the age of Ram be x & Ravi be y, So, age of Mayadevi = 3x and Soham = y/4 Now, x - y = 7..........(1) 3x - {y/4} = 265....(2) From the first equation: y = x - 7 Substitute into the second equation: 3x - {x - 7}/{4} = 265 Multiply through by 4: 12x - (x - 7) = 1060 12x - x + 7 = 1060 11x = 1053 x = 23 Then: Mayadevi = 3x = 3 x 23 = 69 years
