If A had worked alone, he would have taken 60 days to complete a work. If he is joined by B, they complete the same work in 48 days and get paid ₨ 1750. What is B's share?

Rs 350  

                        A    :   A + B

Days                60   :   48          

Efficiency           4   :    5   

Eff. of B = 5 - 4 = 1

B's share = \(\frac{1}{5}\) x 1750 = Rs 350
