Best answer
Correct Answer - Option 1 : 2000

Given:

Each gain = 10%

Third sell = 2662

Concept used:

By Fraction method

Calculation:

Let selling price be Rs. 100

10% gain = 100 + 100 × (10/100) = 110

So, First purchase

⇒ 2662 × (100/110) × (100/110) × (100/110)

⇒ 2662 × (10/11) × (10/11) × (10/11)

⇒ 2 × 1000

⇒ 2000

First pay for earphone Rs. 2000
