Detailed Explanation & Answer
Profit = Income - Investment

Income = Investment + 30% of Investment = 1.3 × Investment

From the table, the profit of Store D in 2020 is 18 lakh.

Let the investment be 'I'. Using the formula:
Profit = Income - Investment
So, 18 = Income - Investment

But since Income = 1.3 × Investment, substitute this into the equation:
18 = 1.3 × Investment - Investment
18 = 0.3 × Investment
Investment = 18 ÷ 0.3 = 60 lakh

Now that we have the investment, calculate the income:
Income = 1.3 × 60 = 78 lakh

Therefore, the income of Store D in 2020 should be 78 lakh to achieve a 30% profit.
लाभ = आय - निवेश

आय = निवेश + निवेश का 30% = 1.3 × निवेश

तालिका से, 2020 में स्टोर D का लाभ 18 लाख है।

निवेश को 'I' होने दें। सूत्र का उपयोग करना:
लाभ = आय - निवेश
तो, 18 = आय - निवेश

लेकिन चूँकि आय = 1.3 × निवेश, इसे समीकरण में प्रतिस्थापित करें:
18 = 1.3 × निवेश - निवेश
18 = 0.3 × निवेश
निवेश = 18 ÷ 0.3 = 60 लाख

अब जब हमारे पास निवेश है, तो आय की गणना करें:
आय = 1.3 × 60 = 78 लाख

इसलिए, 30% लाभ प्राप्त करने के लिए 2020 में स्टोर D की आय 78 लाख होनी चाहिए।
