    Explanation

    Let the present age of Deepa = 5p Let the present age of Hyma = 6p After four years their ratio = 6 : 7 => 5p  +  46p  +  4  =  67\frac{5\mathrm p\;+\;4}{6\mathrm p\;+\;4}\;=\;\frac67 => 35p + 28 = 36p + 24 => p = 4 Therefore, the difference between their ages = 24 - 20 = 4 years.
