Answer:
MP of the article be Rs. x
SP of the article = x × (80/100) = 0.8x
Let the CP of the article be Rs. y, then
y × (10/9) = 0.8x
⇒ y = 0.8x × (9/10)
⇒ y = 0.72x
So, the CP of the article = Rs. 0.72x
According to the question
Profit = 0.8x – 0.72x
40 = 0.08x
⇒ x = 40/0.08
⇒ x = 500
So the Marked price of the article be Rs. 500.
Short trick :
Let CP = 9 unit
SP = 9 × (10/9) = 10 unit
MP = 10 × (5/4) = 12.5 unit
⇒ [10 – 9 = 1 unit] = Rs. 40
⇒ 12.5 unit = 40 × 12.5 = Rs. 500
