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
