A woman bought 120 eggs for #3,000. 20 of the eggs got cracked. She sold the cracked eggs at #21 each and the rest at #30 each. Find her profit or loss percentage.

Answer 1

return = 20(21) + 100(30) = 3420

Since she spent 3000 to buy them and got back 3420 selling them .......

Answer 2

income ... (20 × #21) + [(120 - 20) × #30] = ?

profit/loss ... [(income - cost) / cost] × 100%

Answer 3

You are one key off, $ instead of #.

20($21) + 100($30) - $3000 = ?
