`A` and `B` started a business in partnership investing Rs 20000/- and Rs 15000/- respectively. After six months `C` jointed them with Rs 20000/-. What will be B`s share in the total profit of Rs 25000/- earned at the end of two years from the starting of the business?
A:B:C =(20000$\times$ 24):(15000 $\times$ 24):(20000 $\times$ 18) = 4 : 3 : 3
B`s Share = $\dfrac{3\times25000}{4+3+3}$ = 7500
