₹20 में एक वस्तु को बेचकर, एक विक्रेता 10% का लाभ अर्जित करता है। उसे अपना विक्रय मूल्य (₹ में, दो दशमलव स्थान तक सन्निकटित) कितना बढ़ाना चाहिए, ताकि 20% का लाभ अर्जित कर सके?

3.82 1.82 4.82 2.82

Detailed Solution & Logic

Correct Answer:

1.82

Simple Solution:
Selling price (SP₁) = ₹20
Profit = 10%
So,
$ \text{Cost Price (CP)} = \frac{20}{1.10} = ₹18.18 $
For 20% profit, new selling price:
$ SP_2 = 1.2 \times 18.18 = ₹21.82 $
Increase in selling price:
= 21.82 - 20 = ₹1.82
Answer = ₹1.82
