Method of solving : ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Here, we are given that Out of 100 sums, Rita could do 60 sums correctly. Out of 80 of those sums, Binoy could do 50 sums correctly.

• So, firstly take Ritu's ratio of solving sums and then take Binoy's ratio of solving sums.

Here the ratios of Ritu and Binoy will be :

Ritu's ratio =  

Binoy's ratio =
