The ratio of present age of a father and his son is 7:2. after 5 year the age of son will be 37% of that of his father .The present age of the father is.

Let x be the fathers present age. therefore sons present age = 2x/7 after 5yrs fathers age = x+5 sons age = 2x/7 +5 now sons age = 37% of fathers => 2x/7 + 5 = (x+5)37/100 =>(2x+ 35)/7 = (37x + 185)/100 =>100(2x+35) = 7(37x+185) =>200x +3500 = 259x + 1295 => 59x = 2205 => x= 37.37 yrs

Let present ages of father be x and of son is y years x/y = 7/2 , 2x = 7y , y = 2x/7 (y+5) = 37/100 * (x+5) (2x/7 + 5) = 37/100 * (x+5) (2x + 35) / 7 = (37x + 185) / 100 200x + 3500 = 259x + 1295 259x - 250x = 3500-1295 59x = 2205 x = 37.37 years
