Let x be the common proportionate of both their ages

Then,

Duryodhana's age will be 5x and Dhushyasana's age will be 4x

Their ages five years before would be 5x-5 and 4x-5 respectively

Now,

Case 1:

 \sf{ \frac{5x - 5}{4x - 5} =  \frac{4}{3}  } \\

→15x-15=16x-20

x= 5

Case 2:

 \sf{ \frac{5x - 5}{4x - 5 }=  \frac{3}{2}   } \\

→10x-10=8x-15

→2x= -5

x= -5/2

Case 3:

 \sf{ \frac{5x - 5}{4 x- 5}  =  \frac{9}{7} } \\

→35x-35=36x-45

x=10

Case 4:

 \sf{ \frac{5x - 5}{4x - 5} =  \frac{8}{7}  } \\

→35x-35=32x-40

→3x=-5

x= -5/3

Thus,options (b) and (d) are wrong
