एक वस्तु पर क्रय मूल्य का 210% लाभ होता है। यदि कय मूल्य
में 40% की वृद्धि होती है लेकिन विक्रय मूल्य स्थिर रहता है, तो लाभ
विक्रय मूल्य का लगभग कितना प्रतिशत होगा?
(a) 55%
(b) 62%
(c) 74%
(d) 85%​

Answer 1

Answer:

Assume initial cost $100.

Profit is 210% of cost i.e. $100x210%=210.

Sell Price = $100+$210 = $310.

If cost is increased by 40%, means $100+(40%×%100) = 140.

Revised Profit = $310–$140 = $170

%profit on sale price = ($170/$310)×100 = 54.84%.

Please note that if you make comparison b/w initial and revised profit %, it will be irrational, as initial 210% profit is on cost and revised 54.84% profit is on sale price.

Comparison should be:

210% vs 121% : Based on Profit% on cost; or

67.75% vs 54.84% : Based on Profit % on sale price.
