7. Vijay purchased a 'Sofa Set' at 20% discount on the M.P. If he had bought it with 25% discount​

Answer 1

Step-by-step explanation:

• Let Marked Price = MP
• Let purchased price is SP
• SP = MP(1-20/100) = MP(1-1/5)
• = MP(4/5)
• If discount is 25%
• SP = MP(1-25/100)
• = MP(1-1/4) = MP(3/4)
• Given
• MP(4/5) - MP(3/4) = 500
• MP(16-15)/20 = 500
• MP = 10000
• Price at which sofa set is bought
• = MP(4/5) = 10000*4/5
• = 8000
