The cross, fed a proper cost price

The mean values offered here are all genuine cost prices, already converted from their selling prices. Compare the ₹90 preset with the ₹99 one: the second is the trap, and its ratio corresponds to a blend the trader sells at cost. Doing that comparison once is the fastest way to stop making the mistake.

80 / 110 blended to a cost of 90

2 : 1 · sells at 99 for 10%

Every value here is a cost price per kilo. To use a question's selling price, first divide it by (100 + profit%) and multiply by 100.
