AFCAT Model Paper 8

Given:
On selling an article for Rs. 800, the loss is 1/8 of the profit which is received on selling the article for Rs. 890.
Calculation:
Let the cost price of the article be ‘x’
⇒ (x−800)=(

1

8

)(890−x)
⇒ 8x - 6400 = 890 - x
⇒ 9x = 7290
⇒ x = 810
∴ Cost price of the article = Rs. 810
