If two-third of goods are sold at 25% profit, 20% are sold at 20% loss and rest at a profit of 20%, then there is profit of ₹3312. The cost price of goods is:

₹21,600

Total CP of 150 goods = 150 unit

\(\frac{2}{3}\) of 150 = 100,

20% of 150 = 30

Remaining goods = 150 - 100 - 30 = 20

Total SP of 150 goods = 100 × \(\frac{5}{4}\) + 30 × \(\frac{4}{5}\) + 20 × \(\frac{6}{5}\) = 125 + 24 + 24 =

173 unit

Profit = 173 - 150 = 23 unit

23 unit = 3312

1 unit = 144

150 unit = 150 × 144 = 21600
