Step-by-step explanation:

Let \:  \: Radha's \:  \: age \:  \: be : x \\ Her \:  \: cousin's \:  \: age : x + 19 \\  \\ After \:  \: 5 \:  \: years \\ Radha's \:  \: age \:  \: is : x + 5 \\ Her \:  \: cousin's \:  \: age :x + 19 + 5 = x + 24 \\  \\ x + 5 : x + 24 = 2 : 3 \\  \frac{x + 5}{x + 24}  =  \frac{2}{3}  \\ 3(x + 5) = 2(x + 24) \\ 3x + 15 = 2x + 48 \\ 3x - 2x = 48 - 15 \\ x =  \underline{ \underline{ 33}} \\  \\ Their  \:  \: Present  \:  \: Age \:  \:  is :  \\ Radha's \:  \: age : Radha's \:  \: cousin's \:  \: age  \\ x + 5 : x + 24 \\ 33 + 5 : 33 + 24 \\ 38 : 57 \\  \underline{ \underline{ 2 : 3}}
