Tina alone can do a piece of work in 12 days and Meena can do the same work in 15 days. If Tina and Meena undertook to do this work for Rs 18000 then how much amount will Meena get, if they work together?

Rs. 8,000

LCM of 12, 15 = 60

Let total work be 60

                            Tina   :  Meena

Efficiency                 5     :      4  

Total Wages = ₹ 18000

Wages ∝ Efficiency 

Meena's wage = $\frac{4}{9}$ x 18000

                     = ₹ 8,000
