Question

Determine the profit or loss on the items that was: bought for 670 and sold for 720.​

Answer 1

The CP of first article would be Rs 600 and the second article would be 800.

Let’s say CP of first article was x, then CP of second article would be (1400 - x).

SP of first article = 1.2x (sold at 20% profit)

SP of second article = 0.9 (1400 - x) (sold at 10% loss)

Since both SP are equal,

1.2 x = 0.9 (1400 - x)

On solving for x,

x = 600

So the CP of second article would be 1400 - 600 = 800

Hope this helps. :)
