Ipcc cost-fm nov 2012 paper with solution

Please tell me if my answer regarding this is wrong :

In ratios question, for calculating current assets and current liabilities I did the following :

Working captial = 280000

=>C.A - C.L = 280000

=>C.A = 280000 + C.L

Now,

Current Ratio = 2.4

C.A / C.L   = 2.4

280000 + C.L

____________      = 2.4

C.L

280000 + C.L = 2.4 C.L

1.4 CL = 280000

CL = 280000/1.4 = 200000

CA = 280000 + 200000 = 480000

Here CA = Current Assets and CL = Current Liabilities

I get a different answer here from the solution you mentioned. Tell me which one is correct.

in 1(a) degree of oper  lev is required and not oper lev

@ Sriganesh - here we find that using Inventory, creditor, debtor in other part we obtain a different answer. While using current ratio we find a different answer.

Current ratio given in question is a bit contradictory.

I feel both answer is correct...

sir 

dol  = % change in oper inc / % change in sales

ol = contrib / sales

@ Shashank: OL = Contribution/ EBIT

= % change in operating profit/ % change in contribution

=  % change in operating profit/ % change in Sale

= DOL

DOL is used if income statement is provided in question along with change in level of activity...

k so we cant assmue sales changes from 25000 to 30000
