Sameer takes 30 days to plough a 70 acres land, whereas Rishi takes 18 days to do the same work. Together they complete the work and receive ₨. 2000. How much does Sameer receive out of this?

₨ 750

                        Sameer  :  Rishi

Days                    30      :     18   =  5  :  3               

Efficiency               3      :       5

Sameer's share = \(\frac{3}{8}\) x 2000 = ₨. 750
