Tripti can construct a divider alone in 4 days while Rajan can construct it alone in 3 days. If they construct it together and get a payment of Rs 14000, then what is Tripti's share?

Rs 6000

efficiency ∝ $\frac{1}{time\;taken}$

                   Tripti   :   Rajan

Time               4     :     3

Efficiency        3      :     4     

Since, Wage ∝ efficiency 

Share of Tripti = $\frac{3}{7}$ x Rs 14000

                     = Rs 6000
