Question
A trader buys 120 bags and recovers the cost price after
selling 80 of them. He sells the remaining 40 bags at a profit of 25% and earns Rs. 600 as profit on them. What is the total selling price of the 120 bags?Solution
Let the cost price per bag be Rs. x.
Total CP = 120x.
SP of 80 bags = 120x.
Profit on remaining 40 bags = 25%.
So, 40x × 0.25 = 600
10x = 600 ⇒ x = Rs. 60
Total SP = 120x + 1.25 × 40x
= 120 × 60 + 1.25 × 40 × 60
= 7,200 + 3,000 = Rs. 10,200
