A vendor buys 200 toys at ₹150 each. He finds 10% of them broken and sells them at a 40% loss. The rest are sold at a 20% profit. What is his overall profit or loss percentage?

Explanation

Given: Total toys = 200. Broken = 10% = 20 toys. Sold at -40% profit. Good = 90% = 180 toys. Sold at +20% profit. Formula Used: (n1 × p1 ) + (n2 × p2 ) Weighted Average Profit % = ​ ​ ​ ​ ​ n1 + n2 ​ ​ ​ Solution: Since CP is same for all: (20 × −40) + (180 × 20) Overall % = ​ 200 ​ −800 + 3600 = ​ 200 ​ 2800 = ​ 200 ​ = 14%. Overall profit is 14%. Final Answer So the correct answer is (b)
