Anil bought 100 eggs at Rs.6 per egg. He sold 25 eggs at 10% profit, another 25 eggs at 25% loss and the balance 50 eggs at 20% profit. Find the overall profit or loss percent Anil made?

C.P of 100 eggs = $$100\times\ 6=600$$

C.P of 25 egg = $$25\times\ 6=150$$ Profit = 10%

S.P of 25 egg = $$150\times\ \frac{110}{100}=165$$

C.P of 25 eggs = Rs 150, loss = 25%

S.P of 25 eggs = $$150\times\ \frac{75}{100}=112.5$$

C.P of 25 eggs = 300, profit = 20%

S.P of 50 eggs = $$300\times\ \frac{120}{100}=360$$

Total S.P = 165 + 112.5 + 360 = 637.5

Profit = 637.5 - 600 = 37.5

Profit % = $$\frac{37.5}{600}\times\ 100=6.25\%$$
