The correct answer is (d) 72 yrs.<\/p>\n

Let the present ages of the father and the son be 5x and x years respectively.
\nAfter 12 years, their ages will be (5x+12) and (x+12) years respectively.
\nGiven that the ratio of their ages after 12 years will be 3:2.
\nTherefore,
\n(5x+12)\/(x+12) = 3\/2
\n10x+24 = 3x+36
\n7x = 12
\nx = 12\/7
\nTherefore, the sum of their present ages is
\n5x + x = 6x = 6 * 12\/7 = 72 yrs.<\/p>\n","protected":false},"excerpt":{"rendered":"
