Question 156:

Operating Cost ₹3,40,000; Gross Profit Ratio 20%; Operating Expenses ₹20,000. Calculate Operating Profit Ratio.

Answer:

Cost of Revenue from Operations

= Operating Cost-Operating Expenses

= 3,40,000-20,000

= ₹3,20,000

 

Gross Profit 

 

= 3,20,000×20/80

= ₹80,000

Revenue from Operations

= Cost of Revenue from Operations + Gross Profit

= 3,20,000+80,000

= ₹4,00,000

 

Operating Profit

 

= Revenue from Operations-Operating Cost

= 4,00,000−3,40,000

= ₹60,000

 

Operating Profit Ratio

 

= Operating Profit/Revenue from Operations×100 

= 60,000/4,00,000×100

= 15% 

Question 157:

What will be the Operating Profit Ratio, if Operating Ratio is 82.59%?

Answer:

Operating Ratio = 82.59%

Operating Ratio + Operating Profit Ratio = 100%

Operating Profit Ratio = 100% − 82.59% = 17.41%

Question 158:

Calculate Operating Profit Ratio, in each of the following alternative cases:
Case 1:Revenue from Operations (Net Sales) ₹20,00,000; Operating Profit ₹3,00,000.
Case 2:Revenue from Operations (Net Sales) ₹6,00,000; Operating Cost ₹5,10,000.
Case 4:Revenue from Operations (Net Sales) ₹3,60,000; Gross Profit 20% on Sales; Operating Expenses ₹18,000
Case 4: Revenue from Operations (Net Sales) ₹4,50,000; Cost of Revenue from Operations ₹3,60,000; Operating Expenses ₹22,500.
Case 5: Cost of Goods Sold, i.e., Cost of Revenue from Operations ₹4,00,000; Gross Profit 20% on Sales; Operating Expenses ₹25,000.
Answer:

Case 1

Operating Ratio= Operating Cost/ Net Sales ×100

                   =3,00,000/20,00,000× 100=15%

Case II

Operating Profit = Net Sales- Operating Cost

                   =6,00,000-5,10,000

                   =90,000

Operating Ratio= Operating Cost/ Net Sales ×100

                   =90,000/6,00,000× 100=15%

 

Case III

Net Sales = 3,60,000

Gross Profit = 20% on Sales

Gross Profit =20/100×3,60,000=72,000

Operating Profit = Net Sales- Operating Cost

                   =72,000-18,000

                   =54,000

Operating Ratio= Operating Cost/ Net Sales ×100

                   =54,000/3,60,000× 100=15%

 

Case IV

Net Sales = 4,50,000

Operating Profit = Net Sales- Cost of goods sold-Operation expenses

                   =4,50,000-3,60,000-22,500

                   =67,500

Operating Ratio= Operating Cost/ Net Sales ×100

                   =67,500/4,50,000× 100=15%

 

Case V

Gross profit = 20% on sales

Let Sales =x

Gross profit=x×20/100=20x/100

Sales = Cost Goods Sold + Gross Profit

x=4,00000+20x/100

Or, 80x/100=4,00,000

Or, x=5,00,000

∴Sales = 5,00,000

Operating Cost = Cost of Goods Sold+ Operating Expenses 

                   =4,00,000+25,000=4,25,000

Operating Profit = Net Sales- Cost of goods sold-Operation expenses

                   =5,00,000-4,00,000-25,000

=75,000

Operating Profit Ratio = Operating Profit/ Net Sales×100

                             =75,000×100/5,00,000=15%

Question 159:

Operating Profit Ratio of star Ltd. is 20%. State, giving reason, which of the following transactions will

(a)  Increase (b) Decrease, or (c) not alter the Operation Profit Ratio
