Calculate current ratio from the following
Working capital ?480000
Current assets ?600000
Inventory ?400000
Trade receivable ?150000

Dear student, 
Current assets are given as Rs. 600000
Working capital = current assets- current liabilities
Therefore current Liabilities= current assets - Working capital 
Current liabilities = 600000-480000
=Rs.120000

Therefore the current ratio is $=\frac{current assets}{current liabilities}$
$$\begin{gathered} =\frac{600000}{120000} \\ =5:1 \end{gathered}$$
