Answer 2

Answer:

The cost price of the dealer is 10000 rupees .

Step-by-step explanation:

Marked price of the article is 20000 rupees .

after a 20% discount , the price becomes ( 20000 × 80/100 ) rupees .

after a 10% discount again ,

the price becomes ( 20000 × 80/100 × 90/100 ) rupees .

Let , the cost price of the dealer is C rupees .

amount of money after the 44% gain is ( C × 144/100 ) rupees .

Hence , ( C × 144/100 ) = ( 20000 × 80/100 × 90/100 )

⇒ C = ( 20000 × 80 × 90 × 100 )/( 100 × 100 × 144 )

⇒ C = 10000 rupees
